is it now availabe in lucene?

of indexing Boolean Expressions inside a text indexing
engine is not new. For example Oracle Text provides the CTXRULE index and
the MATCHES operator within their indexing stack, which is primarily used
for Rule-based text classification.
See:

further back, at least to alerting in
Verity K2.

Hi,
I would like to propose implementing Indexing Boolean Expressions (See
http://www.vldb.org/pvldb/2/vldb09-83.pdf) as a Lucene-based project for
GSoC.
Here is a snippet from the Abstract of the paper:
We consider the problem of efficiently indexing Disjunctive Normal Form
(DNF) and Conjunctive
That's a really nice application of DNF and CNF. I'd be happy to work at it
if it gets approved in GSoC.

So if Aayush Kothari is interested in working on this as a Student, all we
need is a formal mentor (I can be the informal one).
Anyone up for the task?
Completely interested in working for and learning about the aforementioned
subject/project. +1.
