lucene query format as plugin

[Brian Whitman <br...@variogr.am>]

Following up on a nutch-user thread from Oct 2006 [1] I am interested  
to hear if there have been any movements in the area of integrating  
more lucene query support into Nutch.

I am particularly interested in queries like

fieldname:(a b c) fieldname:(e f g), i.e. OR-joined field-specific  
multi-term queries.

Via a query-plugin, I've added support for fieldname:a , which works  
fine, but fieldname:a fieldname:b returns only the AND-joined  
results. And fieldname:(a b c) seems to remove both parentheses and  
colon from the query, actually submitting a search for fieldname a b  
c to nutch.

Is there any way to either

(a) add full support for lucene queries via a query plugin, or
(b) add support for field queries that have multiple terms plus OR  
boolean joining?
