Full Text Is Not Working For Me

Nov 28, 2006

Hi all,



I havent found any time difference between the FTS and normal search.

I have created Full text search successfully in wrk_contact table.



CREATE UNIQUE INDEX UI_UKContact ON wrk_contact(id_contact)

CREATE FULLTEXT CATALOG contact_cat AS DEFAULT;

CREATE FULLTEXT INDEX ON wrk_contact(lastname) KEY INDEX UI_UKContact;



I have inserted 1.5 lac of records in that wrk_contact table.



I am trying to do following query



SELECT distinct *
FROM wrk_contact
WHERE CONTAINS(
lastname, '"g*"'
)



Same set of records i have inserted in wrk_contact_tmp table without creating full text search.

I was doing the following query




SELECT distinct *

FROM wrk_contact_tmp

WHERE lastname like 'g%'



I ran both queries seperatly but the execution time for the both queries are same..



Any mistake i made please help me.



Regards

Full Text Search Not Working For Sql2k

Dec 7, 2007

Hi

Issue1:
I have a sql 2k machine. I hav enabled full text indexing on this machine. There after, i inserted and updated so many records. When i do a search using the below query:
It gaves me nothing

select *
from table1
where contains
(
col1,'"keyword"'
)

Issue 2: Another issue is when i gives multiple columns in the below query for search, it throws up a syntax error message at (

select *
from table1
where contains
(
(col1,col2,col3),'"keyword"')
)


Do sql 2k does not allow this format of query(above). But, the same is working fine with one column.

Any inputs on this is highly appreciated.
Thanks!

Full Text Substring Search Not Working

Jul 12, 2007

I have Sql server 2005 SP2.
I enabled it for Full Text search. Substring search where i enter *word* doesn't return any row.
I have a table testtable where description has word Extinguisher.

If i run a query with *ting* it doesn't return any row.
select * from testtable where contains(description,'"*xting*"') ;

But it works if i do
select * from testtable where contains(description,'"Exting*"') ;

The Full text search document says it supports substring search.
Is it an issue with sql server 2005?Please help.

Full Text Index Not Working When Populated From Nvarchar. Bug?

Jul 11, 2007

Hi, I was wondering if any SQL Server gurus out there could help me...

I have a table I'm trying to apply a full text catalog to, however no results are ever returned due to the text column being cataloged being of varbinary(max) that's being populated from a converted nvarchar(max) value.

To re-create the problem quickly...

If I populate the column via
CONVERT(varbinary(max), 'test text')
then there is no problem, I get results as expected.

However if I populate the column via
CONVERT(varbinary(max), CAST('test text' as nvarchar(max)))
no results are ever returned.

Is this a bug with SQL Server 2005 Full Text Indexing? I'm happily creating full text catalogs when an nvarchar is not getting converted into a varbinary.

I'm setting the Document Type column to '.html' (I've tried changing this to '.txt' in case it was a fault with the html ifilter but the problem persists so I believe I can rule this out).

The reason I need to convert an nvarchar to varbinary is that the table holds multi-lingual text and I'm adding a html meta tag <META NAME="MS.LOCALE" CONTENT="ES"> to the beginning in order for the full text indexing word breaker to select the correct language to catalog the text with. The aim being to provide more relevant searches in users native languages (I've read a few articles that describe this technique, but it's the first time I've tried to apply it).

Any pointers / suggestions would be greatly appreciated. Cheers,
Gavin.

Below is a T-SQL script you can run to demonstrate the effect I'm experiencing...

-- Create test database
CREATE DATABASE FullTextTest
GO
USE FullTextTest
GO

-- Create test data table
CREATE TABLE TestTable
(
pk UNIQUEIDENTIFIER NOT NULL CONSTRAINT tablePK PRIMARY KEY,
varbinarycol VARBINARY(MAX),
documentExtension VARCHAR(5),
)
GO

-- The below single entry WILL BE FOUND (the text source is being entered directly)
INSERT INTO TestTable (pk, varbinarycol, documentExtension) VALUES (NEWID(), CONVERT(VARBINARY(MAX),'<META NAME="MS.LOCALE" CONTENT="EN">test entry 1'), '.html')

-- The bellow two entries below WILL NOT BE FOUND (the text source is taken from an NVARCHAR(MAX) value)
INSERT INTO TestTable (pk, varbinarycol, documentExtension) VALUES (NEWID(), CONVERT(VARBINARY(MAX), CAST('<META NAME="MS.LOCALE" CONTENT="EN">test entry 2' AS NVARCHAR(MAX))), '.html')
INSERT INTO TestTable (pk, varbinarycol, documentExtension) VALUES (NEWID(), CONVERT(VARBINARY(MAX), CAST('<META NAME="MS.LOCALE" CONTENT="EN">test entry 3' AS NVARCHAR(MAX))), '.html')
GO

-- Create the full text catalog
sp_fulltext_database 'enable'
GO
CREATE FULLTEXT CATALOG TEST AS DEFAULT
GO
CREATE FULLTEXT INDEX ON TestTable (varbinarycol TYPE COLUMN documentExtension LANGUAGE 1033)
KEY INDEX tablePK
GO

-- NOTE: You might need to give the catalog a chance to build before running the script below.

-- Now do a search that SHOULD RETURN 3 ROWS of data, but ONLY 1 ROW IS RETURNED
SELECT CAST(varbinarycol AS NVARCHAR(MAX)) FROM TestTable WHERE CONTAINS(varbinarycol, 'test')

Upgrade To Advanced Services; Full-text Indexing Not Working

May 8, 2006

I upgraded to Sql Server Express 2005 w/Advanced Services, chose to install full-text indexing, rebooted, but appear to be unable to set up full-text indexing for a column.  After attaching the old mdf file and opening any table in either Management Studio Express or Visual C# Express, I don't get anything but a disabled (Is Full-text Indexed) property for the fields I want to set up.  I have verified that FullText Search service is running, and have tried restarting the service.  I have also checked that full-text indexing is enabled on the database.

I just feel like I am missing some simple step.  Any info would be welcome.

Sql Server 2005 Full Text Search Not Working As Expected On Production Server

Jan 28, 2008

I have this simple full text search query that works perfectly on my own computer using sql server 2005 express, however, on the production server(shared hosting)when I added the first 50+ rows,  the full text search works perfect, but as the number of rows increases,  the full text search can only see the first50+ rows, but not the new ones. Is there any quick solution for this or it's just a common mistake for developers for not properly indexed columns?Is there a way to re-indexed all rows without loosing data on the live server? search query: SELECT TOP 50 *FROM li_BookmarksWHERE FREETEXT(Keywords,@Keywords)

Adding A Full Text Search Across Multiple Tables (with Text Fields)

Sep 7, 2007

Hi, i'm trying to do a full text search on my site to add a weighting score to my results.  I have the following database structure:
Documents: - DocumentID (int, PK) - Title (varchar) - Content (text) - CategoryID (int, FK)
Categories: - CategoryID (int, PK) - CategoryName (varchar)
I need to create a full text index which searches the Title, Content and CategoryName fields.  I figured since i needed to search the CategoryName field i would create an indexed view.  I tried to execute the following query:
CREATE VIEW vw_DocumentsWITH SCHEMABINDING ASSELECT dbo.Documents.DocumentID, dbo.Documents.Title, dbo.Documents.[Content], dbo.Documents.CategoryID, dbo.Categories.CategoryNameFROM dbo.Categories INNER JOIN dbo.Documents ON dbo.Categories.CategoryID = dbo.Documents.CategoryID
GOCREATE UNIQUE CLUSTERED INDEX vw_DocumentsIndexON vw_Documents(DocumentID)
But this gave me the error:
Cannot create index on view 'dbname.dbo.vw_Documents'. It contains text, ntext, image or xml columns.
I tried converting the Content to a varchar(max) within my view but it still didn't like.
Appreciate if someone can tell me how this can be done as surely what i'm trying to do is not ground breaking.

SQL Server 2000 Full Text Search (extract Pieces Of Text)

Sep 12, 2007

Hello everyone !
I want to perform Full Text Search with SQL Server 2000. My documents (.doc, .xls, .txt, .pdf) are stored in a SQL Server field which is binary (the type of the column is image).
I would like to know, how you can extract pieces of text from the documents.
Example:
I have a ASPX page with codebehind in C# making the search in a table in SQL server that is full text indexed.
I make a search looking for the word "peace", than SQL server will take care about the search and return it to me the rows that match with that. But also I'd like to extract the 50 characters before and after where sql server found the word "peace" to show in the result page.
Does anyone has any idea how to work around it ?
 Best regards.
Yannick

Searching Database Text W/o Using Full-text Indexing

Mar 31, 2004

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()

Integration Services :: SSIS Lookup Not Working On Nvarchar Column Using FULL CACHE

Jul 30, 2015

I'm currently loading a package that does a lookup on a column of data type nvarchar(4).The values itself are (A+, A, B+, B, C, D, /). The strange lookup behaviour is happening for each of the cases, so it's not related to a specific value. After trying to put the cache on NO CACHE, the lookup works perfectly. When using the default FULL CACHE the strange behaviour happens. Could it be related to the data type? I have not yet tried to use a CHAR instead of a NVARCHAR but it looks like people have similar issues using CHAR.

Oct 15, 2007

i am tring to create the full text catalog I am following the direction at http://technet.microsoft.com/en-us/library/ms189520.aspx but on the last command it gives me an error

'PK_problem' is not a valid index to enforce a full-text search key. A full-text search key must be a unique, non-nullable, single-column index which is not offline, is not defined on a non-deterministic or imprecise nonpersisted computed column, and has maximum size of 900 bytes. Choose another index for the full-text key.

also I tried the wizard in the managment express but it does not have a option when I right click on the table for Full-Text Index

what am I doing wrong???

SQL Parameters With Full-Text

Jun 24, 2006

Hi,
I have a SQL statement that works great when I don't use a SQL Parameter, but when I do it just takes the @Searchfor as literal text "@SearchFor" instead of the string @SearchFor represents.  Any ideas?  Below is the two versions of the sql statements
sqlComm.Parameters.Add(new SqlParameter("@SearchFor", strSearchFor));
sqlComm.CommandText = "SELECT RANK, intID,  chTitle, chDescription "
"FROM FREETEXTTABLE( tblItems, *, 'ISABOUT("+ strSearchFor +" WEIGHT(1.0))') a " +
"JOIN tblItems b on a.[KEY] = b.intID ORDER BY RANK DESC; ";
 
sqlComm.Parameters.Add(new SqlParameter("@SearchFor", strSearchFor));
sqlComm.CommandText = "SELECT RANK, intID,  chTitle, chDescription " +
"FROM FREETEXTTABLE( tblItems, *, 'ISABOUT(@SearchFor WEIGHT(1.0))') a " +
"JOIN tblItems b on a.[KEY] = b.intID ORDER BY RANK DESC; ";

Full-Text CONTAINS Null

Jul 16, 2006

I have a Full-text search that is being performed on a variable (@Description)  see part of querie below:
WHERE (CONTAINS([Description], @Description)
This search only seems to work when a text fo 3 or greater characters is used Ball, but not for "an" or "a". it also does not search on part of a word i.e. "Gard" of "Garden"
Two things:
1) How do I perform the CONTAINS search for part of a word or "a".
2) How do I perform a search that returns all values, when I leave the input feild blank it returns no records.
Many thanks in advance

Regarding.....Full Text Implementation..........

Sep 21, 2007

I have implemented Full text search in my web application.
I am using sql server 2005 database.
I used “contains “Keyword for full text search.
These are syntax as given below: CONTAINS    ( { column | * } , '< contains_search_condition >'     )  < contains_search_condition > ::=         { < simple_term >         | < prefix_term >         | < generation_term >         | < proximity_term >         | < weighted_term >         }         | { ( < contains_search_condition > )         { AND | AND NOT | OR } < contains_search_condition > [ ...n ]         }  
My search gives correct results according to AND NOT and OR.
But, it is not working if I used AND. 
Please give me solution.
Its very urgent for me……

Full Text Indexing

Sep 30, 2007

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%’â€? 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?
