Hi guys, need your help (again):
I have a search handler which need to override solr's scoring. I chose to
implement it with RankQuery API, so when getTopDocsCollector() gets called
it instantiates my TopDocsCollector instance, and every dicId gets its own
score:
public class MyScorerrankQuet extends RankQuery {
...
@Override
public TopDocsCollector getTopDocsCollector(int i,
SolrIndexerSearcher.QueryCommand cmd, IndexSearcher searcher) {
...
return new MyCollector(...)
}
}
public class MyCollector extends TopDocsCollector{
//Initialized in constrctor
MyScorer scorer;
public MyCollector(){
scorer = new MyScorer();
scorer.start(); //the scorer's API needs to call
start() before every
query and close() at the end of the query
}
@Override
public void collect(int id){
//1. get specific field from the doc using DocValues and
calculate score
using my scorer
//2. add docId and score (ScoreDoc object) into PriorityQueue.
}
}
My problem is that I cant find a place to call scorer.close(), which need to
be executed when the query ends (after we calculated score for each docID).
I saw the DeligatingCollector has finish() method which is called after
collector is done, but I cannot extend both TopDocsCollector and
DeligatingCollector...
