Examples of org.apache.lucene.search.Collector

org.apache.lucene.search.Collector
re scorer public void setScorer(Scorer scorer) { } // accept docs out of order (for a BitSet it doesn't matter) public boolean acceptsDocsOutOfOrder() { return true; } public void collect(int doc) { bits.set(doc + docBase); } public void setNextReader(IndexReader reader, int docBase) { this.docBase = docBase; } });
Not all collectors will need to rebase the docID. For example, a collector that simply counts the total number of hits would skip it.

NOTE: Prior to 2.9, Lucene silently filtered out hits with score <= 0. As of 2.9, the core Collectors no longer do that. It's very unusual to have such hits (a negative query boost, or function query returning negative custom scores, could cause it to happen). If you need that behavior, use {@link PositiveScoresOnlyCollector}.

NOTE: This API is experimental and might change in incompatible ways in the next release.
