Creates a new instance with the ability to specify the body of the SetScorer(Scorer)
method through the setScorer
parameter, the body of the Collect(Int32)
method through the collect
parameter, the body of the SetNextReader(AtomicReaderContext)
method through the setNextReader
parameter, and the body of the AcceptsDocsOutOfOrder
property through the acceptsDocsOutOfOrder
parameter.
Simple example:
IndexSearcher searcher = new IndexSearcher(indexReader);
OpenBitSet bits = new OpenBitSet(indexReader.MaxDoc);
int docBase;
searcher.Search(query,
Collector.NewAnonymous(setScorer: (scorer) =>
{
// ignore scorer
}, collect: (doc) =>
{
bits.Set(doc + docBase);
}, setNextReader: (context) =>
{
docBase = context.DocBase;
}, acceptsDocsOutOfOrder: () =>
{
return true;
})
);
