Full Text Search

Jul 4, 2007

I have a DB in SQL2K5 sp2 which we have a couple of FTC's created.

scenario is as follows

DB1 is a prod DB which has 3 FTC created. This DB needs to be backed up so it can be restored as a QA DB for pre prod roll-out. The QA DB is restored in the same instance as prod. Now with SQL2k5 incoporating the backup of FTC's into the database backup this caused a small problem. The restore has to perfrom the with move and this carries across to the FTC files. However atm the backup is being undertaken at the file level and not copying the FT files. The restore process is using the with Move, once the QA DB is up again i drop the FTC from the QA DB.

1 particular FTC did have a nightly Incremental load happening but this has been stopped for the moment due to these issues.

The QA restore only happens once a wk. When this occurres the restore process sits and hangs (thus making the qa DB unavailable). Using sp_who2 and the activity monitor i have been able to see that the spid for the restore is waiting and has a wait type of 'MSSEARCH'. (From what i have read this is waiting for some action in the MS Search service to complete)

Due to this search wait type when the scheduled backup of DB1 starts it is then hung with a wait type of 'MSSEARCH'. this then leads to increasing connections which leads to blocking and timeouts of the app.

The Restore spid is not able to killed.
The backup spid is not able to killed.
The MS Search Service is not able to be restarted.

The only way i have been able to resolve this is by bouncing the server. Now as this is a prod server this is not suitable.

I have tried that just prior to the full backup starting to stop the MS Search Service but as the FTC's are included into the backup the service obviously needs to be running and the backup process started the service again.

I am at a loss as to what could be causing the FT Service to get itself into a state where it is sitting waiting like this.

Advice help on places to start and look so as to be able to stop and fix this would be appreciated.

thx in advance for you knowledge on this

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;

[Code] ....

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?

Full-Text Search: Prefix / Suffix Search

Sep 14, 2004

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

SQL Search :: Can't Get Expected Results With Contains And Full Text Search?

Nov 1, 2015

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.%';

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

Full Text Search

Jul 23, 2002

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,
Arthur

SQL Full Text Search

Jul 19, 1999

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

Full-text Search

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.

Full Text Search

Aug 8, 2004

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.

Full-Text-Search

Mar 23, 2004

Hi,
I have a full-text search enabled table and an image data type column that stores the extracts from the documents stored in the files. I have created a full text catalog that indexes few columns in the table and image data type column as well and I assigned the extension column to this image data type column.
Everything works fine except that search on the image data type column called, in my case "body" does not return anything. The documents exist, there is an information in the "body" column.

My code goes like this:
select FT_TBL.resourceID, FT_TBL.lang, FT_TBL.keywords, FT_TBL.description, FT_TBL.extension, b.rank
from full_text_search as FT_TBL inner join containstable(full_text_search, *, 'Microsoft') as b
on b.[key] = FT_TBL.resourceID
order by b.rank desc

any help appreciated,
thanks

Full Text Search!!

Jun 23, 2008

Hi,

I need to develop a search application in which each word can be searched as it works in dictionaries. I was thinking of creating a table containing keywords and create an index on them. Since the search is done on some text files I think if it's better to save the files in a table then create another table which holds a reference to the keywords the file has!!
Actually I'm not sure of the best design so any idea is appreciated.
Please lead me to a proper forum topic, if here's not a good place.
