No, you can only index text. It's the same thing as indexing HTML
documents or XML documents. You index "important stuff" from
the guts of the doc.

So, if you can get some text out of these docs, you can index *that*,
possibly along with page information that allows you to, say, display
the relevant page in the original CAD app.

But there's nothing in core Lucene that just takes a CAD doc and
"does magic" to index it that I know of.

thank you for the reply, I knew the answer but was compelled to ask anyway.
CAD files like AutoCad/ProE/CaTia do contain some useful text and it is 
possible to get at that and
index it. But mostly it's vectors and there is not much a text engine can do 
with a vectors.


thanks again.
