Hi,
I have experience some strange things when dealing with Lucene queries.
I've read some threads on this list and realize that Lucene shouldn't be
seen as a complete boolean query language. However I try to understand
the Lucene-way and have one example that I wonder if someone can help me
to clarify.
I wish to create a query that gives me all persons outside us OR having
Smith as last name, ie something like (Country != us or LastName == smith)
This is what I've tried:
+((-Country:us) (+LastName:smith))
results in only all with LastName smith. Ie all the non-Smith's outside
us will not be included.
(-Country:us) (+LastName:smith)
results in all documents. I guess this is since both groups are SHOULD.
It seem to have something to do with the MUST_NOT before Country, since
the query below works more as expected:
+((+Country:us) (+LastName:smith))
results in only all persons in us and all persons in all countries with
last name smith.
Is this not possible to do with Lucene or am I missing something?
Best regards
