collect

public final void collect(int doc,
                          float score)

Description copied from class: HitCollector

Called once for every non-zero scoring document, with the document number and its score.

If, for example, an application wished to collect all of the hits for a query in a BitSet, then it might:

   Searcher searcher = new IndexSearcher(indexReader);
   final BitSet bits = new BitSet(indexReader.maxDoc());
   searcher.search(query, new HitCollector() {
       public void collect(int doc, float score) {
         bits.set(doc);
       }
     });
 

Note: This is called in an inner search loop. For good search performance, implementations of this method should not call Searchable.doc(int) or IndexReader.document(int) on every document number encountered. Doing so can slow searches by an order of magnitude or more.

Note: The score passed to this method is a raw score. In other words, the score will not necessarily be a float whose value is between 0 and 1.
