SQL Server Fulltext search yields no results
I have SQL Server 2005 Express Edition with Advanced Services. I enabled FullText and created a catalog as follows:
create FullText catalog MyDatabase_FT in path 'mypath' as default
I then created a FullText index as follows:
create FullText index on Cell (CellName) key index PK_Cell
with CHANGE_TRACKING AUTO
I executed the following queries:
1) select count(*) from Cell where contains (CellName, 'CU*')
2) select count(*) from Cell where CellName like 'CU%'
And got the following results:
1) 0
2) 24I realize that it could take some time to populate the FullText indexes. However, despite much time (12 hours) I still get no results. I then investigated further using the ObjectPropertyEx() function and executed the following:
declare @id int
select @id = id FROM sys.sysobjects where [Name] = 'Cell'
select 'TableFullTextBackgroundUpdateIndexOn' as 'Property', objectpropertyex(@id, 'TableFullTextBackgroundUpdateIndexOn') as 'Value'
union select 'TableFullTextChangeTrackingOn', objectpropertyex(@id, 'TableFullTextChangeTrackingOn')
union select 'TableFulltextDocsProcessed', objectpropertyex(@id, 'TableFulltextDocsProcessed')
union select 'TableFulltextFailCount', objectpropertyex(@id, 'TableFulltextFailCount')
union select 'TableFulltextItemCount', objectpropertyex(@id, 'TableFulltextItemCount')
union select 'TableFulltextKeyColumn', objectpropertyex(@id, 'TableFulltextKeyColumn')
union select 'TableFulltextPendingChanges', objectpropertyex(@id, 'TableFulltextPendingChanges')
union select 'TableHasActiveFulltextIndex', objectpropertyex(@id, 'TableHasActiveFulltextIndex')
This gave the follo开发者_如何学编程wing results:
TableFullTextBackgroundUpdateIndexOn 1
TableFullTextChangeTrackingOn 1 TableFulltextDocsProcessed 11024 TableFulltextFailCount 0 TableFulltextItemCount 4038 TableFulltextKeyColumn 1 TableFulltextPendingChanges 0 TableHasActiveFulltextIndex 1I then tried to do a fresh full population of the index as follows:
alter fulltext index on Cell start full population
And I get the following warning:
Warning: Request to start a full-text index population on table or indexed view 'Cell' is ignored because a population is currently active for this table or indexed view.
I tried an update population as follows:
alter fulltext index on Cell start update population
This returned: "Command(s) completed successfully.", however I still get no results on the FullText search.
What am I missing? What do I need to do to get the FullText search working?
Thanks, Elan
Well it all boiled down to the formatting of the search text.
This was incorrect:
select count(*) from Cell where contains (CellName, 'CU*')
This was correct:
select count(*) from Cell where contains (CellName, '"CU*"')
Everything is working fine!
