Otis Gospodnetic commented on NUTCH-377:
----------------------------------------

You'd need to modify ./src/java/org/apache/nutch/analysis/NutchAnalysis.jj and regenerate the .java files that produces.

> Searches with boolean operators (AND or OR) are not (yet) possible. All search-items are always searched with AND.
> But it would be nice to have the possibility to allow multiple values for a certain field. Maybe that could done using a separator?
> As an example you might want to search for:
> someword    site:www.example.org|www.apache.org
> Which (to my understand) would allow to search for one or more words with a restriction to those two sites. It would prevent having to implement AND and OR fully (maybe even including brackets) but would allow to cover a few often used cases imho.
> Easy/hard to do? To my understanding Lucene itself allows AND/OR-searches. So might basically be a problem of string-parsing and query-building towards Lucene?
