Indexing documents: how to setup?


I'm new to Lucene, and am trying to setup an advanced search on a Dnn 07.02.02 host. I've got latest version of LuceneSearch, install was ok and searching into standard content is right.

I now want to enable indexing of PDF and office (xlsx, docx) files, but am getting errors and do not know how to go on.
I installed Adobe IFilter v.6 (, and also the 64bit version of Microsoft filters for Office 2007 (
I then had an error that a dll was mising (bcprov-jdk15-1.44), so I found a DLL package at (version 1.8.4, also tried with v. 1.7), but I now have this error when I launch lucene indexing:

I tried substituing all present dll with the same name with the new version from pdfbox package, but am not able to solve.
Can anybody help?

Thank you,

Hi, it might be that last package was incomplete.
I will look into publishing an updated version of the package together with a new Aricie.Shared Package.
I'll let you know when I'm done.

we just released a new package for Aricie Shared which contains the missing dll for the pdf indexing:bcprov-jdk14-132.dll.
I suggest you to remove all the dll of pdfbox and ikvm you've uploaded on your websites. Then, you could install this new version of Aricie Shared and repair the install of LuceneSearch with the original package in order to have the full list of the corrects dll.

I installed the new shared libraries v. 1.8.00, and I confirm it solves the problem for me - no more errors when indexing, thank you!
