示例1: split

FixedBitSet[] split(AtomicReaderContext readerContext) throws IOException {
AtomicReader reader = readerContext.reader();
FixedBitSet[] docSets = new FixedBitSet[numPieces];

}

// FUTURE: if conversion to strings costs too much, we could
// specialize and use the hash function that can work over bytes.
