Full Text Indexing With Japanese Characters Problem
Mar 30, 2006
Hi all,
I am quite experimented with SQL Server, but not that much with full
text indexing. After some successful attempts with english fields, I've
decided to try it with Japanese characters. I don't know why, but it
seems to have a strange behaviour.
As in this screenshot
(http://img65.imageshack.us/img65/980/jap3xt.gif), the CONTAINS
function does not seem to return only fields with an exact word match
of the given "word" (query), but also strange results which does not
even correspond to the query. Can anybody help me with that one?
Thanks! :)

I have set up a full text search to handle multiple columns searching for chinese
But the result of the search isn't really what i have expected.
I have setup the catalog to have a chiense word break, and the columns in the tables are all nvachar
when i do something like
select * from dbo.Table_1 where contains(*, '"<chinese character>"',language 1082)
the search result is really inconsistent, especially with single characters.I have also checked that these characters are not in the noise filter file....
the search result is better when the input is more than a single characters, but still, somtimes it will not return any result at all.
so, I try to use the "like" statement instead of "contains" to do the search with the same inputs, and 100% of the time, it returns the correct result.
does anyone have any experience about things like that? coz I guess this is a more spcific issue with language. Is there any place that you guys know of, can offer me some help?
thank you in advance.

I am using the following plumbing code to search a database column for a keyword. I can't use full-test indexing so I came up w/ this work around. But It has many flaws so I'm looking for a better way. Thx in advance.
'Open sql connection
SqlConnection1.Open()
Dim datareader2 As SqlClient.SqlDataReader
datareader2 = cmdFindRowsWithKeyword.ExecuteReader
Dim strMsg As String
Dim intRowToFlag As Integer
Dim strRowsToGet As String
Dim strKeywordAsTyped As String
Dim strKeywordAllCaps As String
Dim strKeywordAllLower As String
Dim strKeywordFirstLetterCap As String
Dim FirstLetter As String
While datareader2.Read
intRowToFlag = datareader2(0).ToString
strMsg = datareader2(1).ToString
'Assign keyword as typed to variable
strKeywordAsTyped = txtSearchFor.Text
'Assign keyword as typed to variable then convert it to all uppercase
strKeywordAllCaps = txtSearchFor.Text
strKeywordAllCaps = strKeywordAllCaps.ToUpper
'Assign keyword as typed to variable then convert it to all lowercase
strKeywordAllLower = txtSearchFor.Text
strKeywordAllLower = strKeywordAllLower.ToLower
'Assign keyword as typed to variable then convert it so just the first letter is in uppercase
strKeywordFirstLetterCap = txtSearchFor.Text
FirstLetter = strKeywordFirstLetterCap.Chars(0)
FirstLetter = FirstLetter.ToUpper
strKeywordFirstLetterCap = strKeywordFirstLetterCap.Remove(0, 1)
strKeywordFirstLetterCap = strKeywordFirstLetterCap.Insert(0, FirstLetter)
'If the string contains the keyword as typed in all caps all lowercase or w/ the 1st letter in caps then flag that row.
If strMsg.IndexOf(strKeywordAsTyped) <> -1 Or strMsg.IndexOf(strKeywordAllCaps) <> -1 Or strMsg.IndexOf(strKeywordAllLower) <> -1 Or strMsg.IndexOf(strKeywordFirstLetterCap) <> -1 Then
cmdFlagRowsWithKeyword.Parameters("@recid").Value = intRowToFlag
SqlConnection2.Open()
Dim datareader3 As SqlClient.SqlDataReader
datareader3 = cmdFlagRowsWithKeyword.ExecuteReader
datareader3.Close()
SqlConnection2.Close()
End If
End While
datareader2.Close()

full text indexing
Hi,
In SQL Server 2005, if I set full text indexing enables in column MyDesc and
1. use “Select * from MyTable where MyDesc LIKE ‘%abc%’� would this be using full text indexing? Or have to use Contains to get it be in use?
2. Once I create the full-text index, should I be setting it to populate periodically? Isn’t it populating itself?

How might it be possible to have on the fly full-text indexing utilizing the FREETEXT and CONTAINS statements so that when I enter a piece of data into the database it is immediatly searchable using the full-text indexing features?

Recently the full text catalogs no longer work on my sql server. We have tried a lot of different things to get them working and all have failed. I am totally at a loss. The service is running under the local admin and the local admins have sysadmin permissions. We have removed the catalogs and re-added them. We have removed the catalogs changed the DB to disable full text indexing. Checked the registry for the left over entries. Run sp_fulltext_service 'clean_up'. We have tried many difference combinations and tried restoring from backup. Nothing works. If anyone has ANY ideas I would greatly appreciate the help. We are running SQL 7.0 with SP3.

I have a table of product inventory I want to be able to search using the CONTAINS and/or FREETEXT functions. There are actually 4 columns I want to be searchable: brand, product name, etc. Since the table can have only one full-text index, should I just define an index on all 4 columns? It would be large in relation to the table, but the table itself is small (~600 rows). The index would not exceed the 900 byte limit.
Will this give me problems in terms of workability or performance? Is there a better approach? I could also just use LIKE searching, but it's significantly less sophisticated.
Thanks in advance.

Hi,
I am working on programming a knowledge base using ASP and MS SQL and we're running into the problem of how to search it... In that past we've just had a type of like statement... but this isn't really a search function and isn't really doing the trick...
So, what I'm thinking is that we might be able to use the full-text indexing service on Microsoft SQL server and then somehow search the full-text index from an ASP page and then procede with the db interface from there.
Are there better ways of searching MS SQL databases which I'm not aware of? Is it possible to access the full-text index from an ASP page and how would you do this? Are there documents that people could recommend on how to setup full-text indexing on MS SQL Server?
Thank you in advance, ( )

Hello everyone,
My questions are about installation (setup) and perfromances.
I have seen that, by default, all database user's files are set to : Use full-text indexing.
If we don't use full-text search at all, would it be a good idea to turn it off?
It seem impossible to turn it off at database creation using the T-SQL : CREATE DATABASE statement. Is it?
Having this parameter set to ON by default must incur an overhead. Rigth?
Best regards.
Carl

Trying to make a full-text table of a few tables in SQL server 2000 using the SQL Server Managment Studio. I am getting the following error when I then try to view the columns using the table. The column it is having a problem with is just a varchar text column. I have tried a few different tables and each time it has a problem with one of the columns. It does not give me an error when creating the full-text table. Anyone have any information on this?
I check on a full text table I made a while ago and it is giving me the same error but searches on it seem to be working, but cannot tell if it is using the one column it is having an issue with.
Property TypeColumnName is not available for FullTextIndexColumn '[MyColumnName]'. This property may not exist for this object, or may not be retrievable due to insufficient access rights. (Microsoft.SqlServer.Smo)

Hey guys,
I'm about to deploy full-text searching to complement
ASP.NET/C#.NET. I unfortunately have not had much experience in
Full-Text Indexing...
I will be creating catalogs for each table in the database (end-users
pretty much require that we are able to search by
anything). I see that there is a catalog population
schedule...typically, what is the best practice for updating the
catalogs? The database entries will most likely be updated
frequently, as it contains the end-users curriculum vitae. Would
once a day, say midnight, be a sufficient schedule?
And also, as it pertains to best practices, is the method I am applying
the best way to do this (a catalog per table)...I have about 30 tables
in a relational model...is there a better way to catalog the entire
thing instead of table by table?
Thanks a lot for the help!
Eric...

I was trying Full text indexing on my database. it seems to work fine on all databases except one. On one particular database it returns '0 results' immediately even though the table has a large number of records.
The search returns just fine if tried on the same table on a different database on a different server.
Does anyone have a faintest clue as to what could be wrong ?
please reply ASAP.
Thanks

I am having a few tables in my database on which I am implementing
FullText Searching.
As the tables are huge, full population of the catalog takes a lot of time.
I want to go for incremental population but I did not have a timestamp column
for this purpose when I initially designed the database.
Is there any way to ensure incremental population without the timestamp column? Because of the design constraints I do not like to have a timestamp column and would like to avoid it if it is possible.
But with out that SQL performs a full population and it is taking more than two hours now for full population and I also have several databases on which I have to do the same but the structure is more or less the same.
What are the performance issues when users are accessing the database when full text catalog population is in progress?Does it slow down reads and writes?It is a web based application for the internet catalog for industrial suppliers and needs to be online with no performance degradation.
Any help and info on this is greatly appreciated.
Thanks

I'm attached to two different SQL 7 servers and neither one has the options enabled for full-text indexing. I am the DBO for those databases and the services are running.
Any ideas what's missing? I'm using SQL 7 clients tools on my NT Workstation.
Also, are there samples of using the index/search within ASP?

Hi,
I am using full text indexing to index an image column where I am storing HTML documents. Currently I have an extra column in my table storing the file extension (htm) so the indexer knows which filter to use for every row.
HTML is the only format I'll be indexing, so is there a way for me to set this somewhere else so I don't have to have a column full of htm values - this seems really wasteful, those htm's add up when there are millions of rows...
Thanks!

I have been trying to set up full-text indexing. All the CONTAINS searches, however, always returns 0 row. It seems the index is always empty. Could you please help figure it out?
Here is how I created the full-text catalog and index:
CREATE FULLTEXT CATALOG ft_catalog AS DEFAULT;
CREATE FULLTEXT INDEX kb(title, body) KEY INDEX PK_kb WITH CHANGE_TRACKING AUTO;
Then from the full-text crawl log, I found
