Thanks for the reply. Everything is working correctly now. I jumped the gun without debuging it
more. booleanANDSearch was not getting set correctly.

I don't see a problem with your booleanANDSearch thingy, although
I haven't tried it.
Does toString() return the same string regardless of the value of
booleanANDSearch? That would surprise me. The default
is OR, so the toString output looks like booleanANDSearch is false.
In general, the Lucene syntax is
no symbol SHOULD
+ MUST
- MUST_NOT
If this doesn't help, could you give us the toString for your
query1 and query2?

I am new to Lucene and am having problems with booleanQueries. How do you
write Boolean OR and AND
queries?
Is this an OR query
booleanQuery.add(query1, BooleanClause.Occur.SHOULD);
booleanQuery.add(query2, BooleanClause.Occur.SHOULD);
and is this an AND query
booleanQuery.add(query1, BooleanClause.Occur.MUST);
booleanQuery.add(query2, BooleanClause.Occur.MUST);
Is there a problem writing it this way so I can change between the two by
setting booleanANDSearch
to true or false
booleanQuery.add(query1,(booleanANDSearch?BooleanClause.Occur.MUST:
BooleanClause.Occur.SHOULD));
booleanQuery.add(query2,(booleanANDSearch?BooleanClause.Occur.MUST:
BooleanClause.Occur.SHOULD));
Also, when I call booleanQuery.toString(), I am getting this:
(upc:creatine description:creatine content:creatine) (brand:gluten
brand:free) (category:alc
category:beer)
It looks like each grouping is a query but how are the queries connected,
with AND, OR or NOT?
