You can use the "Section Content-Type" command in indexer.conf,
for example:

Section Content-Type            12      64

Then at search time you can limit searches for certain file types only,
with help of the "type" HTML form variable.

For example:

http://yoursite/search.cgi?q=test&type=application/pdf

will search for the word "test" in PDF documents only.
