Full-Text Indexing a PDF file with Sql Server 2005 December CTP (aka Yukon)

I just got finished installing and setting up the full-text indexing of a pdf file for Sql Server 2005 December CTP Build.  Here are the steps to getting it working (assuming you have a functioning table to store BLOB data).

  1. Remember that your table must have a BLOB field, such as a varbinary(max), and a column to specify the file type to the full-text index create index commands or the full-text index wizard in Sql Server Management Studio.
  2. Download and install the Adobe Acrobate PDF Filter.  It is available at http://www.adobe.com/support/downloads/detail.jsp?ftpID=2611.
  3. Execute the following commands against your Sql Server 2005 instance.
    • sp_fulltext_service 'load_os_resources',1.  This command tells the Microsoft Search Service to load OS specific wordbreakers, stemmers, and such.
    • sp_fulltext_service 'verify_signature', 0.  Do not verify that the binaries are signed.
  4. Bounce the Sql Server Service and MSFTESQL.
  5. Create your full-text index.
  6. Issue the necessary command(s) to (re)index.

Hi Wally,
This was posted by a Dev Lead when simalar advise was given on a fulltext newsgroup thread: "This will work, but beware that making this change makes your SQL instance a little less secure. Be sure to read the documentation for these flags so you understand the risk."

From the Yukon BOL title "sp_fulltext_service" - "Enabling use of OS resources provides access to resources for languages and document types registered with Microsoft Indexing Service that do not have an instance-specific resource installed."

Basicly, you need to set this when adding a new IFilter, but should disable it when you're finished, i.e., set it backe to:

sp_fulltext_service 'verify_signature', 1
sp_fulltext_service 'load_os_resources',0

Even FTS, now has to keep SQL Server secure ;-)

When will be released the Yukon version for the public?

Is there any way to index pdf files in SQL2000?

thanks

It works basically the same except that you have use an image column instead of a varbinary(max).

Hi,

I have to search through six PDF documents stored in a particular location. The input for the search is a keyword text and the output should be the bookmarks under which the text is present(for each section and subsection a bookmark will be present in the PDF). Preferably, the percentage of match also needs to be displayed against each bookmark link. How do I achieve the same? Any help would be greatly appreciated.

Thanks,
Vijay

Use Index Server if you are looking at indexing the some pdfs on the file system.

Hello,

I use the full-text search utility in SQL Server 2005 to find word in PDFs document.

This is my 'Documents' table:

id (PK), data (VarBinary(max)), extension (nvarchar(4))

My full-text catalog on 'data' column works fine because when I search 'Microsoft', my document containing this word is returned as result.

SELECT * FROM Documents WHERE freetext([data], 'Microsoft');

1 , 0x255044...., .pdf

But I need to know how many times 'Microsoft' word appears in this document.

Do you have any idea how can I retrieve this information?

Thanks in advance!

Hello Korgoth,

I need to do the same thing, i e, count how many times a specific word appears in a document.

Did you discover how to do that using MSSQL Fulltext index?

Wally, this did the trick for me.  I recently migrated an older app over from 2000 to 2005 and the fulltext search stopped working on PDF's stored as blobs.  I uninstalled the IFilter, ran those commands, and reindexed.  Bingo!

Thanks!
