Troubleshooting SQL Server Full-Text Search Problems
9. Error about ignored words
If you encounter errors indicating that the full-text query contains only ignored words, try to rewrite this query to a phrase-based query, removing the noise words.
You will get an error indicating that the full-text query contains ignored words when the CONTAINS predicate is used with words such ‘OR’, ‘AND’ and ‘BETWEEN’ as searchable phrase.
For example, this select statement returns error:
SELECT ProductName FROM Products
WHERE CONTAINS(ProductName, ‘and OR between’)
10. Rewrite English Query’s questions, so that these questions will not require a full-text search on a table with a uniqueidentifier key.
Asking English Query’s questions that require a full-text search on a table with a uniqueidentifier key may cause English Query to stop responding.
11. BackOffice 4.5 issues
If you decide to install the full-text search by using the BackOffice 4.5 custom setup, after a successful installation of SQL Server 7.0 (without installing full-text search), you should run Setupsql.exe from the BackOffice CD-ROM(2) (SQL70Machine_platformSetupSetupsql.exe)
You are not allowed to do it by using the BackOffice 4.5 setup, because the BackOffice Custom Installation dialog box falsely indicate that the full-text search has been installed already.
12. Time Out Errors
If you encounter an error indicating that the full-text query has timed out, try to reduce the size of the result set, or increase the ‘remote query timeout’ setting, or insert the full-text query result set into a temporary table instead of streaming the results directly to the client.
13. Make a single column unique index for the table you want will be used in a full-text query.
Full-text indexing cannot work on a table that has a unique index on multiple columns. If the table you want will be used in a full-text query does not currently have a single column unique index, add an IDENTITY column with a UNIQUE index or constraint.
14. Upgrade to SQL Server 2000, if you need to work with full-text search in a clustered environment.
Full-text search is not available in a SQL Server 7.0 clustered environment.
