Also used the following without a problem:

bool_query.add(q,true,false);

Hi,
I haven't tried two levels of boolean queries but I did use the following
and it works fine for me.

BooleanQuery bool_query = new BooleanQuery();
for each field
{
Query q = QueryParser.parse(term,field,analyzer);
bool_query.add(q,false,false);
}
searcher.search( bool_query);

Subject: "Match All Words" Query


Hi!

I've been going round in circles trying to come up with a query that will
return documents which contian ALL the query terms. This should be easy,
however I would like the words to span ANY of the fields of the documents.

If the BooleanQuery(ies) do actually follow boolean logic, then I should be
able to form this query:

BooleanQuery b = new BooleanQuery();

for each term in the query {
BooleanQuery sub_query = new BooleanQuery();
for each field {
Query q = QueryParser.parse(term,field,analyzer);
sub_query.add(q,false,false); <----
disjunction of fields
}

b.add(sub_query,true,false); <---- conjunction of terms
}

And then b *should* be the query.

However, the query does not give the desired results!

Probably most all users of Lucene have needed such a query... I feel i'm
complicating things here!

Help would be greatly appreciated.

Melissa.
