Query Parser Syntax documentation now available
Lucene supports creating your own query syntax, but also provides a default
QueryParser implementation using JavaCC to parse query strings into Lucene
Query objects.
In hopes to provide some better understanding, there is now a Query Parser
Syntax document available which describes the features of this
implementation and some examples.
http://jakarta.apache.org/lucene/docs/queryparsersyntax.html
It is also located in the resources menu on the Lucene web site.
I hope this proves helpful.

Re: Latent Semantic Analysis?
Posted by John Caron <ca...@unidata.ucar.edu>.
Hello Lucene Developers:
I have been lurking on this list for a while, and this question is good
excuse to introduce myself. I have an implementation of LSA that I have been
planning to modify to fit into the Lucene framework Real Soon Now. I would
be interested in collaborating with others, or just hearing how it should
work and/or design thoughts.
Ive been thinking about LSA as a search algorithm; i have some other ideas
about clustering, but havent had time to test any of them.
Some details of previous LSA work are available at:
http://www.unidata.ucar.edu/staff/caron/faqo/index.html
(in fact, if you look at the FAQO demo, you will notice that I've been
archiving this maillist since Oct, so you can try LSA out on it. PS: sorry i
dont have any real docs yet, but have a look at the online help).

Latent Semantic Analysis?
Posted by Jack Park <ja...@thinkalong.com>.
I tried googling "latent semantic lucene". Got nowhere. Just a curiosity,
is there a project 'out there' that is looking at adding clustering,
perhaps using LSA to Lucene?

The choice is between 1.2 and 1.3; 1.1 is ancient history and 1.4 is
still bleeding edge from a commercial perspective.
The majority of sites have moved to 1.3, but the differences in coding
between 1.2 and 1.3 are minor. I would suggest 1.2.
