Indexing select Office 2007 (Visio/OneNote) and Zip files with MOSS

I was asked the other day why Visio documents weren’t being indexed properly (you couldn’t search inside documents for certain terms).

As it turns out, a default installation of MOSS doesn’t include iFilters for Microsoft Visio. Nor do they have them for OneNote or Zip files. Go figure, OneNote and Visio are Microsoft products.

In December, Microsoft released the Microsoft Filter Pack, which contains the relevant filters. Once you install the filters on your index server (it’s a simple installation), you will need to do some registry edits and restart the search service. Complete instructions can be found here.

NOTE: I’ve been told that SP1 already includes a OneNote filter by default, so if you’re running that you may not need to do this.
