Hi Steve and how want help,
in this direction I added boost to fields, a bit different of in
queryParser like you suggestion, but I have some quastions:
1- If I set boost to a fields they are sum to be used like doc.boost ?
2 - If field1_boost=2 and field2_boost=1 and query match to field1 in
document 1 and to field2 in document2, document1 and document2 have
the same score (when I use multfieldquery) ?
