No Results Returned For Full Text Search On Varbinary(max) Column
Jul 10, 2007
Hi, I was wondering if any SQL Server gurus out there could help me...
I have a table which contains text resources for my application. The text resources are multi-lingual so I've read that if I add a html language indicator meta tag e.g.
<META NAME="MS.LOCALE" CONTENT="ES">
and store the text in a varbinary column with a supporting Document Type column containing ".html" of varchar(5) then the full text index service should be intelligent about the language word breakers it applies when indexing the text. (I hope this is correct technique for best multi-lingual support in a single table?)
However, when I come to query this data the results always return 0 rows (no errors are encountered). e.g.
DECLARE @SearchWord nvarchar(256)
SET @SearchWord = 'search' -- Yes, this word is definitely present in my resources.
SELECT * FROM Resource WHERE CONTAINS(Document, @SearchWord)
I'm a little puzzled as Full Text search is working fine on another table that employs an nvarchar column.
Any pointers / suggestions would be greatly appreciated. Cheers,
Gavin.

I am using Sql Server 2014 Express edition.I have a table with a varchar(max) column. I have created a full text search that use the stoplist "system". column has this struct: xxx.yyy.zzz.... where xxx, yyy, zzz... are numbers, like 123.345.123123.366456...I can have rows like that:
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 MyCOlumn like '123.345.%';
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 - I've narrowed it down to this specifically, populating with non nvarchar text seems to work fine.To re-create the problem quickly...If I populate the column viaCONVERT(varbinary(max), 'test text')then there is no problem, I get results as expected.However if I populate the column viaCONVERT(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.

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

-- 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')
My full-text search isn't working at all! I have a temporary table with full-text indexing enabled where files are scanned for social security numbers. If it has one, the user will see a message that it believes it's found a SSN and won't upload it. There is only ever one row in this table, as we overwrite the contents upon each upload.
I'm testing this search, and it doesn't work. The table has the following columns: attachemtId (int) - primary key fileContent (image) - contents of the file fileExtension (varchar) - extension of the file (this is always either ".pdf" or ".doc")
I created a .doc file that simply says "ssn", and then run the following query:
SELECT * FROM TempAttachment WHERE CONTAINS(fileContent,'ssn')
and nothing is returned! I tried the same thing with a .pdf file, and same results.
I'm not sure if this is related, but earlier I had this issue where I had to reset permissions for the directory. I've tried removing the full-text index and adding it again, but that didn't do anything. I also checked error logs on the server, and there were no messages. Any help would be appreciated! Thank you!
We have a table that is Full Text Search index enabled on one column.This table has 200 lakhs of rows(20000000) . ContainsTable() function is searching data with in these 200 lakhs of rows(20000000), if any new rows are inserted then the ContainsTable is not going to search in these recent inserted rows.
We observed when we try for a data to search. it is returning the rows till the rows that are inserted date is less than 30th of march 2012. but not searching in the records that are created after April month , if even the data we are searching is available .
TableFulltextItemCount is around 2.2 crores.
Then we done rebuilt the FT catalog Index. then the TableFulltextItemCount became 0.Again we run the containstable query ,but still it is not getting results.
As the no of rows are very more . so i am not able to show the actual rows from which the data is not coming.
the below query gives 2 results that are from actual base table
HTML Code: select * from g_case_action_log where cas_details like '%235355%' and product_id = 38810
To search for the same above word using FTS,I have used the query as below
HTML Code: SELECT Distinct top 50 cal.case_id,cal.cas_details From g_case_action_log cal (READUNCOMMITTED)inner join containstable(es.g_case_action_log, cas_details, ' ("235355" OR "<br>235355" OR "235355<br> ") ') as key_tbl on cal.log_id = key_tbl.[key] Where cal.product_id = 38810 ORDER By cal.case_id DESC

I have a FullTextSQLQuery which I am trying to search a phrase(The Multi-part identifier) on full text indexed table. I am getting expected results on running the below sql query on QA machine and PreProduction servers, but not getting the same results on our development and production servres as even though same code running.
SELECT DISTINCT TOP 50 c.case_id,c.status_id,cal.cas_details FROM g_case_action_log cal (READUNCOMMITTED) INNER JOIN g_case c (READUNCOMMITTED) ON (cal.case_id = c.case_id) INNER JOIN CONTAINSTABLE(es.g_case_action_log, cas_details, ' "The multi-part identifier" OR "<br>The multi-part identifier" OR "The multi-part identifier<br>" ') as key_tbl ON cal.log_id = key_tbl.[key] ORDER By c.case_id DESC
We are using SqlServer 2008 R2 version on all servers.
We are running SQL 2014 SP1. We are using defined Full text indexes on several tables in the database. However, on one specific set of servers, a certain search will not return any data. This exact same search works on another set of servers built identically. The first responses I'm sure will be stop list, but I have dropped and recreated the FTI multiple times with different stop lists or no stop list at all and get the same results.
The specific word being searched on is YUM. If I change the value to YUMk, it actually returns, and if I change the data to TUM it returns, but YUM does not. This exact query is working on multiple other systems, so it seems to be something environmental, but I haven't been able to pinpoint it.
I have written this sample query to search a full-text indexed table and return the results. If the word occurs more than once I want it to return as a new record and the results show a short summary of the location. I was using 'like', but the full table scans were really slowing it down. Can performance be improved for the following (The results returned by my query are accurate)
Can anybody provide an example of how to specify a column list in a CONTAINS statement? Documentation says it must be comma separated inside parenthesis - I have tried (every combination of) this but always get the error "Incorrect syntax near '('.", for example:
SELECT .... WHERE CONTAINS((Name,Description), '"options"')
This works fine when just querying one column (without the parenthesis).
I'm trying to use CONTAINSTABLE to do a product search on a number of columns. I want matches on some columns to be weighted higher than for other columns.
It seems like there should be a way to do this with CONTAINSTABLE - I know I can search by multiple strings and weight those matches variably, but what I want is to vary the weight by which column a single term matched. What I have now is a series of UNION queries, which are quite slow: =================== SELECT m.TitleCode, m.ShortName, m.ShortDescription, a.Rank, 50 as theWeight FROM CONTAINSTABLE (Product, ShortName, @theSearchTerm) as a, Product m(NoLock) WHERE a.[KEY] = m.TitleCode
UNION ALL
SELECT m.TitleCode, m.ShortName, m.ShortDescription, a.Rank, 40 as theWeight FROM FREETEXTTABLE (Product, ShortName, @theSearchTerm) as a, Product m(NoLock) WHERE a.[KEY] = m.TitleCode
UNION ALL
SELECT m.TitleCode, m.ShortName, m.ShortDescription, a.Rank, 30 as theWeight FROM FREETEXTTABLE (Product, MatchKeywords, @theSearchTerm) as a, Product m(NoLock) WHERE a.[KEY] = m.TitleCode
UNION ALL
SELECT m.TitleCode, m.ShortName, m.ShortDescription, a.Rank, 20 as theWeight FROM FREETEXTTABLE (Product, ShortDescription, @theSearchTerm) as a, Product m(NoLock) WHERE a.[KEY] = m.TitleCode
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
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;
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?
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?
I have installed the Adobe iFilter 11 64 bit and set the path to the bin folder. I still cannot find any text from the pdf files. I suspect I am missing something trivial because I don't find much when I Bing for this so it must not be a common problem.Here is the code.

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.
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.
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

Hi friends i work with sql server 2005 express(Management Studio) can i use full text search service with that edition of sql server? and how i can use that. thank u.
I am asking about installing Microsoft Search service in SQL Server 2000 in Windows XP Professional Is that possible? And By the way it's not possible for me to switch to SQL Server 2005 that I know that full text indexing already exists in it
After following all of the steps in Swynk's Guide to Full Text Search, I still can't seem to retrieve any records from the full-text search. I get messages saying that I created the Index correctly and that I successfully populated the catalog. But when I View the Properties of the catalog, the Unique Word Count = 1 (but there are thousands of words in the table). I know that there is a record with the word "help" in one of the full-text indexed columns, but when I call Contains(column-name, 'help'), I recieve an empty recordset.
Does anyone have any suggestion on what I can try next?
My Prod. server is having SQL Server 7.0 with SP2 installed. I am planning to install Full Text Search component. I know I have to run setup and select Full Text Search from Server Components. But, Do I have to re-install service pack 2 after this ? What are the other concerns in, such modifications to the existing SQL installation ?
