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?
