Hi
I know how to get the docFreq of a term in a single field (say "content" field)
int docFreqInIndex = indexReader.docFreq(new Term("content", q));
But is it possible to get the docFreq of a boolean query consisting of matches
across two or more fields? For instance,
BooleanQuery booleanQuery = new BooleanQuery();
booleanQuery.add(new BooleanClause(new TermQuery(new Term("content", q)) ,
Occur.MUST));
booleanQuery.add(new BooleanClause(new TermQuery(new Term("publisher", q2)) ,
Occur.MUST));
docFreq API does not accept a booleanQuery.
docFreqInIndex = indexReader.docFreq(booleanQuery);
what would be the best solution to this?
thank you
