An issue with Full Text Search against PDF blobs... Camilo
8/9/2007 3:26:18 PM
sql server full text search: My client is trying to use SQL Server Full Text Search to search PDFs stored
in a varbinary(max) column. Full text search works fine for other Microsoft
Office documents stored in the same table but it does NOT give back any
results from the PDF documents.

Following is a high-level view of what the client did:

1. Installed Adobe PDF IFilter 6.0
2. Ran the stored procedure sp_fulltext_service (as documented)
3. Restarted the server
4. Verified that the filter got properly installed by querying the system
view
sys.fulltext_document_types
5. Created a full text index on the table with the documents
6. Started a full population of the index
7. Ran a sample query with a string he knows is in the PDF file like the
following:
select * from documents where freetext(document, ‘Review’) and got no
results
back
8. Ran the same sample query with a string he knows is in some Word files
like the
following: select * from documents where freetext(document, ‘SQL’) the
query
returned several rows back as expected.

Does anybody know what might be happening here?

Thank you!

Russell,

No, we are using a 32-bit machine in this case.

I did make FTS work with PDF files by creating a new table, importing the
data, creating a new catalog and populating it again.

Thanks!

Camilo,

Are you using 64-bit Windows and SQL Server? If so, last time I looked the
Adobe PDF IFilter was only 32-bit.

Check the gatherer logs to see what the status of your population was.
