Indexing Service stopped searching on PDF contents after editing NOISE files in Server 2008 (32 bit) of an ASP.NET Application

amazursky used Ask the Experts™

We have our ASP.NET application installed on a Server 2008 (32-bit). One of the module is to do the extended search in the contents of all the pdf and word files loaded into our application.

We configure Indexing Service with ifilter 6 to do it for us.

On one of our Server we edited all the NOISE files, placed in /system32/ folder, to remove few tags to support our searching context. Since then the Indexing service is not returning the search result related to the contents of the PDF files.

We re-installed IFilter6, we reconfigured the Indexing Service, We reinstalled the Adobe Reader 9.0 to make it work but nothing worked.

Can some expert help us out in this situation?

Uninstall iFilter one more time..

Use Revo Unintaller (Comodo uninstaller) should work too.  I think there are portable versions of these unisntallers..  Reason I say to use a third-party uninstlaler is that there maybe files and/or registry settings left over.

Restart your system..  I know you may not be able to do that so easily.  :)

Re-install iFilter..  Re-Build your index.


Hi, Kent!

We tried REVO uninstaller to uninstall Ifilter but it didn't solve the issue.

I have solved the issue by working into registory entries. The fix has nothing to do with the Ifilter but with the Adobe Reader versions. There were multiple paths set in the registery for diff Versions of Adobe Reader. So i deleted unncessary entries for other versions and it solved the issue.



The problem happened because of different versions of Adobe Reader paths set in Registory. We just fixed it by removing unncessary paths and keep the one that is installed.
