OK, I just took a look at Text::Query. From what I can tell from reading
the docs and the source, it looks as though it's a brute force text scanner
rather than an inverted-index generator. So that means it's about 3 to 4
orders of magnitude slower than what I need. :-( (But it still looks nice
for small bodies of text (say, less than a megabyte) :-)
For dynamic content like news, the must-have's of an index and retrieval
system are:
- Rapid retrieval of matches (this implies an inverted index on disk).
- Rapid incremental, real-time indexing (the index should not have to be
rebuilt from scratch periodically).
- Low to moderate disk consumption (say, less than 2x the original overall
content size).
- Easily handle from 100MB to 10GB of indexed text.
This is what I have now, but its top-level interface isn't very smart; it
doesn't do soundex or stemming or fuzzy matching or "funny characters."
Here's a product which (I'm not considering but) sounds like a something that
would work great on gobs and gobs of content like news:
http://www.1source.com/~pollarda/findex/
If I can find something like that which comes with source, then that would be
a good alternative what I cobbled together.
