Have a look at Aperture: http://aperture.sourceforge.net/
It provides components for crawling and text and metadata extraction.
It's still in alpha stage though. The development code in CVS has
already improved a lot over the last official alpha release.

I think that Nutch would crawl and search all these 3 types. Not sure that
Nutch would provide the framework you seem to look for, but perhaps it is
worth to take a look - http://lucene.apache.org/nutch/

Re: which way to index pdf,word,excel

First, Lucene is just a index toolkit, you have to USE it to implement your
application.
If you want to index something, you must have knowledge how to extract
information from them and what kind of keys they need to be set.
Then you can do what you want to.

Thanks Andrzej, I understand the concepts involved now. If the need
arises, I'll see what I can do about making it work as intended.

You can write a HtmlParseFilter, which will extract these portions of
text and put them into ParseData.metadata. Then, during indexing you can
check if such metadata exists and if yes - add it as separate fields.
You will need also to modify the QueryFilters, to expand user queries to
also include clauses for these additional fields.

I thought a workaround like that would be needed. Still, it could give
useful results...though as a nutch user, the possibility is mostly
theoretical for me, as probably none of the existing parsers take into
account the formatting information. I could be completely wrong here,
so please, feel free to correct me.

No, it can't (at least not yet). As a workaround you can extract these
portions of text to another field (or multiple fields), and then add
them with a higher boost. Then, expand your queries so that they include
also this field. This way, if query matches these special tokens,
results will get higher rank because of matching on this boosted field.

Which brings me to another (off)topic: can lucene/nutch assign
different weights to tokens in the same document field? An obvious
example would be: "this text seems to be in large, bold, blinking
letters: I'll assume it's more important than the surrounding 8px
text."

Support for editing and adding things to PowerPoint files is limited, as
is getting out the finer points of fonts and positioning.
Getting text out should "just work" for you. The only thing you'll need to
decide is if you want hslf.PowerPointExtractor to give you slide and notes
text, or just slide text :)

http://jakarta.apache.org/poi/hslf/index.html
It doesn't say poi doesn't support ppt. It just says support is
limited. Don't know exactly how limited, but certainly not useless for
indexing purposes.
Don't know if the plugin works, though. :)

Did you check POI javadocs? Look for
org.apache.poi.hslf.extractor.PowerPointExtractor. It's one of the most
straightforward classes from POI as far extracting text for indexing is
concerned.

Indexing MS Powerpoint files with Lucene
Posted by Venkateshprasanna <pr...@yahoo.co.in>.
Is there any filter available for extracting text from MS Powerpoint files
and indexing them?
The lucene website suggests the POI project, which, it seems does not
support PPT files as of now.
