Keyword Search Program

Sep 11, 2003

Hi,

I am in the middle of developing procedure for keyword search for our website.

Input parameter is a string consisting keywords in comma delimited format.

This is the example of data I get from business group which I use to populate my key_search table.

product_id keyword
1 Microsoft, training
1CA, DBA
1CA, developer
1CA, network admin
1AZ, DBA
1AK, developer
1MN, DBA
1MN, developer
1OH, developer
2Microsoft, training
2AZ, DBA
2AZ, developer
2IL, developer
2MN, DBA
2CA, developer
2NY, business analyst
2NY, DBA
2NY, developer
2NY, programmer
3Oracle, training
3finance
4Oracle demo
4logistic
4Oracle Financials
4Financial Analyzer

They have provided search string examples like 'Microsoft, DBA, CA'
or 'CA'
or 'Microsoft, developer' or 'training'

I have script ready to remove comma from the string and store words from the input string in a temporary table.
But this is the easiest part.

The Confusing part now for me is to write the optimal code for retrieving the exact match from the key_search table as there is no limit on how many words can be in the string, it can be 1, 2, 3 or more.

Any suggestions on how should I handle this search?

Keyword Search

May 27, 2007

I am trying to implement a band search on my web site (concert listings) and would like it to behave a bit more intelligently than a standard match on the band name.
At the moment I have a stored procedure that just selects every show that features a band with exactly the same name as the search term. What I'm now trying to do is when the user enters a band name containing the '&' character I would also like to search using the word and 'and'. For example, if they search for 'Rise & Fall', they should get details on all shows featuring 'Rise & Fall' OR 'Rise And Fall'. Is it possible to do this within my stored procedure?

Search By Keyword

Jan 31, 2008

 Greetings,  I am a php developer, and running a little bit out of deadline in a project. Can someone provide me with a VERY simple way to implement search by keyword in C#?  I have already implemented a search page (according to firstname, lastname etc) that works on a drop down menu (where you have the option to choose seach by keyword) . So, I need to change something in my SQL query to make this work. I already knew from my SQL experience that the simplest and probably the SLOWEST and MOST UN EFFICIENT one was using LIKE. I don't mind using it but I can't since I will end up  having something close to that: SELECT * FROM users WHERE keyword_entered LIKE @keyword;      (or '@keyword)  which does not work.      however SELECT * FROM users WHERE keyword_entered LIKE 'somename%'; does work! I guess the trick is in putting the % after the keyword. ( I would have done that in php by putting the entered keyword in a string and than add to it % and pass it to the SQL query and I dunno how to do that in .NET)any ideas?

Keyword Search

Apr 18, 2008


Hi,

I have a table like

ProductId, Description, Description2

where Description and Description2 are text datatypes.

I'm trying to return all records where myKeyword exists as a singular word in either of these two fields.

Should I create a child table where each word in each of these fields has its own row for each product and query against that or is there an efficient way of querying this result without creating the extra child table?

Many thanks for any pointers

Dan

How Do I Program A Search Engine?

Feb 23, 2008

I heard that making a search engine involves PHP programming. I would like to know how to program a secure well developed image search engine for my website. Are there any websites or books you could recommend? I know a little C-sharp, but I think a beginners book in PHP would be better than an advanced or novice one. I understand this may be in the wrong forum but I figured it may involve some MySQL

Large Keyword Search

Apr 11, 2005

I’m working on a project that will allow a user to search through approx 100,000 records in a SQL table. Three of the columns are ‘text’ fields that hold paragraphs of text. The user interface has a ‘general search’ option so that they can enter a number of key words and the database will return a count of the records found containing the keywords.
At the moment I split the input and then build a query based on their input. For instance if they enter ‘hello world’ the input is split into two strings ‘hello’ and ‘world’. I then build the query in a loop and get a query like so:
Select Count(ID) as myCount FROM myTable WHERE (colOne like ‘%hello%’ AND colOne like ‘%world%’) OR (colTwo like ‘%hello%’ AND colTwo like ‘%world%’) OR (colThree like ‘%hello%’ AND colThree like ‘%world%’)
Unfortunately this query runs EXTREMELY slowly and just seems wrong. Is there a more efficient way I should be doing these types of searching? This method works ok on 100 records, but this is the first time I have worked on such a large database.
Is it also possible to search a text column and look for exact matches?
For instance I have 2 records with their textfield containing:
Rec 1: the news for today is blah blah. Rec 1: this is a new item
If I currently search for ‘new’ (select colID from myTable where colOne like ‘%new%’) I will get both these records, but I’d really only like to pull out the second record.
Any help would be great appreciated! :)

Multi Keyword Search SP

Jul 23, 2005

Is it possible to write a Stored Procedure that takes a string ofsearch keywords as argument and returns the recordset? At the mo I ampassing the WHERE String as argument.I got this technique from an Extreme Ultradev tutorial by Rick Curtisit looked quite ok:http://www.princeton.edu/~rcurtis/u...tutorial12.htmlI have to admit, one of the main reason for passing the WHERE string isthat I do not know how to do the string splitting / parsing and puttingtogether in a Stored Procedure. I bet T-SQL would be just as powerfulas VBScript if I just knew it well enough.What I liked about having built them on the web script was theflexibility allowing to potentially build an advanced search withouthaving to change the stored procedure - but this is not crucial I couldalways write several stored procedures or add parameters to the SP.Here is what I have achieved in this way:User can enter one ore more keywords separated by space.Search algorithm returns results across a number of fields where ALLsearch words are contained in any of these.Search results will always be formatted a certain way and displayed ina html table no matter how the search procedure / criteria is varied.Here is the algorithm (that now works in ASP)1. split search string into separate keywords2. build where condition based on single keyword, concatenating allsearched fields (" AND f1+' '+f2+{' '+f<n>} LIKE %<keyword>%")3. concatenate all these where conditions and pass to stored procedure.4. stored procedure takes care of all other logic (e.g. Joins, whichfields are searched etc.). It uses a string variable @SQL to build thecomplete search string and then doesexecute (@SQL);to create the recordset.I bet there is a way to move 1. 2. and 3. into the SP (and I would feelbetter if it was) but I don't have the expertise to do this. If anybodywants to help me this is very welcome.I can also post my original code to clarify, just want to avoid toolong posts.CheersAxel

Search For Keyword In Database

Mar 14, 2008

Hii

I want to search for a keyword in the database.
The database has approximately 30 tables and the amount of data in tables is very large. Most of the tables hold 25000 rows. The search procedure for searching a keyword that i want to use is as below. When i executed the stored proc it took 20 minutes. What i want to know is full-text search a better option than this or is there any other way out.


CREATE PROC SearchAllTables

CREATE TABLE #Results (ColumnName nvarchar(370), ColumnValue nvarchar(3630))

SET NOCOUNT ON

SET @TableName = ''

SET @SearchStr2 = QUOTENAME('%' + @SearchStr + '%','''')

WHILE @TableName IS NOT NULL

BEGIN

SET @ColumnName = ''

SQL Server Search-and-replace Program

Apr 21, 2006

I found a search-and-replace program for SQL server that works GREAT, but I have a list of about 200 words to search for, with corresponding replacements. Rather than editing the code below for *each* word and running it 200 separate times, I'd like to iterate through the list, but my MS-SQL programming skills are...light (to say the least). Anyone have any ideas how I can create a list or hash-type variable and use the code to loop through and do the replacements all at once?

/*
*
* Search & Replace
*
* Use Ctrl+Shift+M to replace template values
*
*/

set xact_abort on
begin tran

declare @otxt varchar(1000)
set @otxt = '<string1, text, text to be replaced>'

declare @ntxt varchar(1000)
set @ntxt = '<string2, text, replacing text>'

declare @txtlen int
set @txtlen = len(@otxt)

declare @ptr binary(16)
declare @pos int
declare @id int

declare curs cursor local fast_forward
for
select
id,
textptr(<field_name, sysname, target text field>),
charindex(@otxt, <field_name, sysname, target text field>)-1
from
<table_name, sysname, target table>
where
<field_name, sysname, target text field>
like
'%' + @otxt +'%'

open curs

fetch next from curs into @id, @ptr, @pos

while @@fetch_status = 0
begin
print 'Text found in row id=' + cast(@id as varchar) + ' at pos=' + cast(@pos as varchar)

updatetext <table_name, sysname, target table> .<field_name, sysname, target text field> @ptr @pos @txtlen @ntxt

Fulltext Search With Contain Keyword In Server

Sep 25, 2013

I'm using full text search in sql server 2008 with contain keyword.

My issue is while I'm trying

select * from tbl_item_master where contains (ITM_FULLTEXT,'red and white')

above syntax gives me required output but while I'm trying

select * from tbl_item_master where contains (ITM_FULLTEXT,'red and the and white')

above syntax does not gives me output. I'm using system stop list and "the" is noise keyword.

I want to stop searching "the" but want result as per first syntax.

I do get warning " The full-text search condition contained noise word(s)."

Is it possible?

Multiple Keyword Search In A Stored Procedure

Sep 8, 2006

 Hi Guys, I hope someone here can help me. I am writing a stored procedure that simply searches for a given value across multiple databases on the same server. So far all well and good.Now, the problem is if the user types in more than one word into the search field.I have put a partial section of code here, there is obviously more, but most of it you wouldn't need to see. SELECT @sql = N'SELECT @count = COUNT('+ @dbname +'.dbo.orders.order_id) FROM '+ @dbname +'.dbo.orders '+
N' INNER JOIN '+ @dbname +'.dbo.customer ON '+ @dbname +'.dbo.orders.cust_id = '+ @dbname +'.dbo.customer.cust_id '+
N' WHERE '+ @dbname +'.dbo.customer.forename LIKE ''%'+ @SearchStr + '%'' OR '+ @dbname +'.dbo.customer.Surname LIKE ''%'+ @SearchStr + '%'''

EXEC sp_executesql @sql, N'@count int OUTPUT', @count = @results OUTPUT Now this code works perfectly well if the user only enters one word, however i need to make sure that the Stored procedure will function if the user enters 2 words, such as John Smith. I need the procedure to search the forename for 'john' & 'Smith' and the same for the surname. It should also work if the user type 'John Michael Smith' - if you understand.I am really struggling with this one.Thanks in advance.Darren

Need Links For Multiple Keyword Search Solutions Please

Jun 6, 2008

I have been informed that all my keyword search solutions are susceptible to SQL injection attacks.  Does anyone have links discussing basic ' multiple ' keyword search solutions?  I would think this is a very common routine (perhaps so much so than only newbies like myself do not know it).  I have read the posts about escaping ', doing replace " ' ", " '' ", using parameters and yet every multiple keyword solution I come up with is said to be injection prone.
Example: visitor enters:  Tom's antiquesinto a TextBox control and the C# code behind securely generates the below call to the database.
SELECT L_Name, L_City, L_State, L_Display FROM tblCompanies WHERE L_Kwords LIKE '%' + 'Tom's' + '%' AND L_Kwords LIKE '%' + 'antiques' + '%' AND L_Display = 1 RETURN
I understand that concantenting string parts using an array and then passing the sewn together string to a stored procedure exposes it to injection.  I hope that my single keyword routine below is secure, if it is not then I am not understanding how parameterized SP are supposed to be constructed to protect against injection.string CompanyName;CompanyName = TextBox1.Text;PROCEDURE CoNameSearch @CompanyName varchar(100)AS SELECT DISTINCT L_Name, L_Phone, L_City, L_State, L_Zip, L_Enabled, L_Display FROM tblLinksWHERE (L_Name LIKE @CompanyName + '%') AND L_Enabled = 1 AND L_Display = 1 ORDER BY L_NameRETURN

Compensate For Keyword Density In Full Text Search

Apr 8, 2008

Hi,

When using FREETEXTTABLE the RANK returned seems to be partially based on keyword density. Has anyone come across a method of compensating for this keyword density so that good matches found in a lot of text and a small amount of text return the same RANK?

For an example look at the site I'm working on when someone searches for "whale watching" - http://www.yougodo.com/Search.aspx?ks=whale+watching - you can see that we are showing poor quality results at the top as our first sort order is based on RANK.

If we could remove the keyword density factor from RANK then this would allow second order sorting criteria to come in to play and move the more valuable results to the top.

Any help, pointers, advice would be greatly appreciated,
Gavin.

SQL 2000 MS Search: Boolean Search Doesn't Work When Search By Phrase

Aug 9, 2006

I'm just wonder if this is a bug in MS Search or am I doing something wrong.

I have a query below

declare @search_clause varchar(255)

set @Search_Clause = ' "hepatitis b" and "hepatocellular carcinoma"'

select * from results

where contains(finding,@search_clause)

I don't get the correct result at all.

If I change my search_clause to "hepatitis" and "hepatocellular carcinoma -- without the "b"

then i get the correct result.

It seems MS Search doesn't like the phrase contain one letter or some sort or is it a know bug?

Anyone know?

Help W/ Stored Procedure? - Full-text Search: Search Query Of Normalized Data

Mar 29, 2008

 Hi -  I'm short of SQL experience and hacking my way through creating a simple search feature for a personal project. I would be very grateful if anyone could help me out with writing a stored procedure. Problem: I have two tables with three columns indexed for full-text search. So far I have been able to successfully execute the following query returning matching row ids:  dbo.Search_Articles        @searchText varchar(150)        AS    SELECT ArticleID     FROM articles    WHERE CONTAINS(Description, @searchText) OR CONTAINS(Title, @searchText)    UNION    SELECT ArticleID     FROM article_pages    WHERE CONTAINS(Text, @searchText);        RETURN This returns the ArticleID for any articles or article_pages records where there is a text match. I ultimately need the stored procedure to return all columns from the articles table for matches and not just the StoryID. Seems like maybe I should try using some kind of JOIN on the result of the UNION above and the articles table? But I have so far been unable to figure out how to do this as I can't seem to declare a name for the result table of the UNION above. Perhaps there is another more eloquent solution? Thanks! Peter

SQL Search :: Full Text Search With Single Character Returns All Rows

Jul 21, 2015

Our clients want to be able to do full text search with a single letter. (Is the name Newton, Nathan, Nick?, Is the ID N1, N2...). Doing a single character full text search on a table work 25 out of 26 times. The letter that doesn't work is 'n'. the WHERE clause CONTAINS(full_text_field, ' "n*" ') returns all rows, even rows that have no 'n' in them anywhere. Adding a second letter after the "n" works as expected.

Here is an example

create table TestFullTextSearch (
Id int not null,
AllText nvarchar(400)
)
create unique index test_tfts on TestFullTextSearch(Id);
create fulltext catalog ftcat_tfts;

SQL Server 2014 :: Semantic Search Not Finding Keywords Identified By Full-Text Search?

Nov 6, 2014

I have a scenario of where the standard Full-Text search identifies keywords but Semantic Search does not recognize them as keywords. I'm hoping to understand why Semantic Search might not recognize them. The context this is being used in medical terminology and the specific key words I noticed missing right off the bat were medications.

For instance, if I put the following string into a FT indexed table

'J9355 - Trastuzumab (Herceptin)'
AND
'J9355 - Trastuzumab emtansine'

The Semantic Search recognized 'Herceptin' and 'Emtansine' but not 'Trastuzumab'

Nor in

'J8999 - Everolimus (Afinitor)'

It did not recognize 'Afinitor' as a keyword.

In all cases the Base of Full-Text did find those keywords and were identifiable using the dmvsys.dm_fts_index_keywords_by_document.It does show the index as having completed.

why certain words might not be picked up while others would be? Could it be a language/dictionary issue? I am using English and accent insensitive settings?

Create Site Search Using Sql Server Full Text Search

Jul 24, 2007

would you use sql server "full text search" feature as your site index?  from some reason i can't make index server my site search catalog, and i wonder if the full text is the solution. i think that i wll have to you create new table called some thing like "site text" and i will need to write every text twice- one the the table (let's say "articles table") and one to the text. other wise- there is problems finding the right urlof the text, searching different tables with different columns name and so on...
so i thought create site search table, with the columns:
id, text, url
and to write every thing to this table.
but some how ot look the wrong way, that every forum post, every article, album picture or joke will insert twice to the sqr server...
what do you think?

SQL 2012 :: FullText Search - Can Search Terms Come From Another Table

Mar 25, 2015

I have a table that contains words that will be used to search another table where FullText index has been created on searchable columns. I'm basically trying to run something like this:

SELECT t1.col1, t2.col3
FROM tbl1 t1, tbl2 t2
WHERE CONTAINS (t1.col1, t2.col1)

I know this won't work but is there a way to join these two tables so the words (t2.col1) can be passed as search conditions? There is no common key on both tables so normal join won't work. I'm trying to find a way to pass the search words from one table to another.

I am trying this query:

select * from Mytable where
contains(MyColumn, '123.345.')

I gues the contains would return all the rows with column contains 123.345, but this does not return all the expected rows, only one row.I have tried to replace "." with "-" but the result is the same.I have also tried with '123.345.*. In this case I have got more results, but no all the exptected rows.If I use this query:

select * from MyTable where

How To Search A Database For A Key Word Based Search?

I basically have a database that has a qualifications column and this column needs to be searched for the data given in the textbox. Which is the best method to search for the data? Is it a simple SQL query or an XML based search engine type? Can anyone give any suggestions regarding this? If XML is efficient then how do I use it to query my database, as I'm pretty new in XML based searching.Thanks
