Indexing Software

[Mark Herschberg]

Does anyone know of any indexing software? A discussion in the author's corral suggested a need for this. There is commercial software out there, but it seems rather old and expensive.
If there isn't any and someone is interested in starting one, someone has suggested an algorithm (since he worked on a commercial system, I don't want to name him/her, since we may latter offer the algorithm s/he suggested) which is pretty basic. It's mostly an issue of handling the data formats (e.g. Word, PDF, LaTex) and doing basic String parsing.

Is Lucene the kind of Indexing you mean?

Yep, that's what I'm looking for. Thanks!
