Take ANTLR and roll your own query parser from scratch? It's pretty

Hi Earwin,
That would be fantastic, since our parser is already specified as an
ANTLR grammar. However, I can't seem to find an antlr grammar in the
lucene source. Obviously what we want is to extend the existing query
support, not just create a new one from scratch.

Hello,
I'm looking at a way to extend the lucene query parser to allow for
semantic
computations in IEML space (see http://ieml.org). What I'd like to
know is:
how difficult it would be to be able to add clauses to query
like: ... AND (
some_IEML_expression) AND ...
some_IEML_expression would involve a reference to some field that
would
contain metadata expressed in that format.
Thanks in advance for you insights.
