View 1 RepliesHow much overhead is incurred with a full text search? I am thinking of creating a "keyword" table and doing it by hand?
View 1 RepliesFull Text Searches are working on my test server, but not on my production server. My test scenario is as follows:
CREATE FULLTEXT CATALOG FTC_Test
AS DEFAULT
AUTHORIZATION dbo
CREATE FULLTEXT INDEX ON guest.FtsTest(FullName)
KEY INDEX PK_FtsTest ON FTC_TestI wait briefly and then check to see if the index has been populated:
SELECT * FROM sys.fulltext_indexescrawl_end_date is not null,
So I'm assuming I don't have to wait anymore before I try some FTS searches. Right? I can't get any queries to return anything, though.
The following tells me the full text item count for the table is zero:
DECLARE @TableId INT
SELECT @TableId = id FROM sys.sysobjects WHERE [Name] = 'FtsTest'
SELECT OBJECTPROPERTYEX(@TableId, 'TableFulltextItemCount') AS TableFulltextItemCount
As mentioned, the full text search works on my test server. Both of them are SQL 20012 SP1 (11.0.3000) x64 running on WinServer 2008 R2 SP1.
I'm using the Full Text Search with the neutral language in the indexed columns. I have no stoplists so everything counts. We changed to neutral language because our customers don't have the need for language specific criteria. They just want raw text search.Everything was working great but then they found a term that they can't search and I can't figure out what's wrong. It comes down to this:
SELECT * FROM sys.dm_fts_parser('"1.2.3.4"', 1033, NULL, 0);
SELECT * FROM sys.dm_fts_parser('"1.2.3.4"', 0, NULL, 0);
In the neutral language, the parser will return "3.4", differently than the English language parsing.In the 1033 language, the parser will break all the numbers into words and the result will show correctly.I really don't want to change the language from neutral because it's working for every other query.
I am new to Full-Text Searches and FileTables. I am working on a resume search system. I created a FileTable and the Share which contains about 51,000 resumes in Word (DOC/DOCX), PDF and TXT formats that were copied over from our main file server. I followed the instructions on adding the Microsoft Filter Pack 2.0, and all searchable file types are listed in sys.fulltext.document_types.
I have a program that searches resumes by First and Last Name and/or E-mail Address. For a while, we thought it was working fine because we were getting hits, but then we noticed some Names and E-mail Addresses we new existed were not showing up in my CONTAINS queries -- but we verified the documents do exist and the Names exist in the File Name and inside the document along with the E-Mail address.
One example I'm working on now cannot find the First/Last Name with CONTAINS(name,"lastname") in a Word DOC file, but I can find the document using LEFT(name,5) = 'Smith'. It's a Word DOC file. For testing purposes, I opened the DOC file in Word, then used Save As to create a TXT and DOCX file within the same folder. Now, both of those are showing up in the CONTAINS but not the original DOC file.
I'm standardizing street addresses and i think full text search, maybe, work fine with my problem. My problem is that I have 2 millon of errors and using "LIKE" dont work correctly. This is what i have now:
UPDATE addresses
SET standarAddress = REPLACE (addresses.streetAddress, errors.streetAddress, corrects.streetAddress)
FROM corrects
INNER JOIN errors
ON corrects.id = errors.idCorrects
[Code] ....
I am doing a web app on the full text search.My select statement using CONTAINS but it doesn't seem to return all the string that contains the search word I included in the query.For example:
Select CustomerID, customername,
from CustomerTable
where CONTAINS ((CustomerID), '"430*")
the query result only return all customer id which has space in front 430 or start with 430
ex: "xxx 430xxx" or "430 xxx" or "xxx 430 xxx"
but did not return customerID which doesn't has space in front of it
Ex: x430xxx
If I use LIKE '%430%', the result return are both have space in front and don't have space in front.
Is there a way to make full text search which supports search terms for words with symbols, like C#, C++ etc.?
I see that even this forum, if I try search for C++, it returns everything where letter c exists. So, it's not possible I guess?
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)
Query
DECLARE @searchString nvarchar(255);
DECLARE @searchStringWild nvarchar(275);
SET @searchString = 'first';
SET @searchStringWild = UPPER('"' +@searchString+ '*"');
SELECT id, '...' + SUBSTRING(searchResults.MatchedCell, searchResults.StartPosition, searchResults.EndPosition - searchResults.StartPosition) + '...' as Result
[Code] ....
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
View 3 Replies View RelatedOur 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;
[Code] ....
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?

How can I search throught DOCX (MS Word 2007) documents by SQL Server 2005 Full Text Search engine?

Please help me to create an SQL Server 2000 Stored Procedure for using prefix and suffix terms.
Example:
Say I want to find "Terminator" (1984).
I want to be able to use "Term" or "ator" as search results and still return the proper record.
Here is my Stored Procedure creation sql:
CREATE PROCEDURE sps_searchTitles(@searchTerm varchar(255)) AS
SELECT * FROM Video
WHERE FREETEXT (Video.*, '"*@searchTerm*"')
GO
--- The above does not appear to properly check both prefix ("Term---") and suffix ("---ator") terms.
I am trying to accomplish what is similarly done with LIKE '%term%'.
thanks, YM
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.
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:
123.345
123.345
123.345.444
123.345.555
123.345.666
123.345.444.777
123.345.444.888
123.345.555.999
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
MyCOlumn like '123.345.%';
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
for example:
SELECT * from [table1] WHERE CONTAINS([msgcomment], '"fast" NEAR "performance"')
would always slower than
SELECT * from [table1] WHERE [msgcomment] = '%fast%performance%'
Why? and how can it be solved? can you help me?
:)
I'm experiencing an anomaly with my Full text index.
Setup : SQL Server 2005
Indexed Table:
Assets
ID - int (PK, auto increment)
Ref - varchar(50)
[code]....
I have re-built the full-text index, no change.
Are there any big differences between the two search techniques? It seems like they are both very similar.
SELECT * FROM TABLE1 WHERE TEXTFIELD1 LIKE '%DATABASES%'
SELECT * FROM TABLE1 WHERE CONTAINS (TEXTFIELD1 ,' "DATABASES" ')
Hi I have a full text index on my product table.

Thanks My query:SELECT * From Product WHERE FREETEXT (description, @SearchString)

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
thanks
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?
Thanks for any help,

Hi,
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 ?
Thanks
Greetings ! Has anyone seen a problem in SQL 7 where you create a full text catalog, define an index on a table, and run 'populate', and end up with an empty catalog ? It runs for a while during the population, and there are no messages in the logs, but the 'item count' property of the catalog is 0.
Also you can run a query that uses the index (i.e. uses 'CONTAINS') and you receive no error, and no results.
I've set this up on other servers, so I know it works, but can find no mention of this problem anywhere.
TIA
Eric
Hi, I got a problem in my SQL2000 server full-text search function. When I created the full-text catalog and index on tables, I got the message showing it is successful. But when I checked the properties of the catalog, I found "item count" is zero. Apparently, it didn't populate any data into index. What could the possible reason be? Any idea? I appreciate your comments.

Hi everyone
I am using SQL server 2000 with SP3 on Windows 2003 server.
I have scheduled a job to populate a full text index incrementally. Everytime it runs the job to populate the index table it writes some messages into event log.
Like this:
1.
Event Type : Information
Event Source : Microsoft Search
Event Category: Gatherer
Event ID : 3019
Date :8/7/2004
Time :2:21:00 PM
User : N/A
Computer : ARC-03-DEV
Description:1
The crawl on project <SQL Server SQL00002000009> has started.
2.
Event Type : Information
Event Source : Microsoft Search
Event Category: Gatherer
Event ID : 3047
Date :8/7/2004
Time :2:21:00 PM
User : N/A
Computer : ARC-03-DEV
Description:
The end of the incremental crawl for project <SQL Server SQL00002000009> has been detected. The Gatherer successfully processed 998 documents totaling 0K. It failed to filter 0 documents. 998 documents were modified. 0 URLs could not be reached or were denied access.
The event log is getting filled frequently.
Is there any way to stop this messages?
It is normal for Microsoft Search to write this message into EventLog?
Even though there is no chanage in the database it give the above messages.
Any one know the reason please help.
Quick reply is appreaciated.
