Hi everyone,
I searched an index with 3 its' fields({"name", "addr", "fullname"}), and used
DisjunctionMaxQuery to rank the results by the max score of 3 fields. When the
hits have same score, lucene would rank by doc Id(low doc Id would be front).
But I don't want rank by doc Id in that case. I would rank by field. If the
hits have same score, I expect that the hit which's score (max score) is from
field "name" is front to the hit which's score is from other field.
I think the customer Collector & HitQueue is good idea and rewrite the method
PriorityQueue.lessThan could change rank in priority queue. Unfortunately, the
info in ScoreDoc is too less. And it's hard to get the source of max score for
every hits.
Someone else know how to solve it? Thx!
Regards,
