Thanks Adrien!
1) Here is my code snippet:
Query params_vendor = new ConstTermQuery(new Term("params_vendor",
queryStr), 5f);
Query params_model = new ConstTermQuery(new Term("params_model", queryStr), 5f);
Query params_value = new ConstTermQuery(new Term("params_value", queryStr), 3f);
Query par
Hi Vadim,
A Weight is the specialization of a query for a given index reader. It has
access to index statistics that will help compute scores for instance.
A Scorer is the specialization of a weight for a given segment. It can
iterate over matches and compute scores.
The cost of a scorer is the
