Add possibility to search for multiple values
---------------------------------------------

                 Key: NUTCH-377
                 URL: http://issues.apache.org/jira/browse/NUTCH-377
             Project: Nutch
          Issue Type: Improvement
          Components: searcher
            Reporter: Stefan Neufeind


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?
