I'm using a very simple filter prog to index Winword Docs on our servers:

    FileFilter  .doc

----- snip --------
# -- <docfile>

cat $1 | strings
---- snap ---------

You are getting occasionally some garbage characters - escpecially when 
images are included. But it's sufficient for indexing the doc.

Additionally I've got a private response pointing to a tool called "catdoc".

BTW: Some words to swish++
  So far I've only read the Readme file (some weeks ago).
  But for my personal flavor swish++ is lacking some features I want to
  see (e.g. Config Files) at this moment.

  But I've a wish list for swish-e, too... ;-)
