Hi Jan,
Basically, DrillDown is a helper class for creating such queries. You're
right that its query() methods create AND, because that's normally the
case, but if you require OR, you could do this:
BooleanQuery res = new BooleanQuery();
for (CategoryPath cp : paths) {
res.add(new TermQuery(DrillDown.term(iParams, cp)), Occur.SHOULD);
}
I copied the code from DrillDown.query(FacetIndexingParams,
CategoryPath...) and modified Occur.MUST to Occur.SHOULD.
Can you give it a try?
