"Match All Words" Query

[Melissa Mifsud <me...@yahoo.com>]

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.

Just a thought... have you tried building a string that'll do the query you
require and then letting the QueryParser create the actual query object(s)?

If that works, then delve into the QueryParser code and see how it does what
you're trying to do...

cheers,
