                                                      throws IOException

Create a new ES91OSQVectorsScorer for the given IndexInput.

Throws:

IOException

                                                        throws IOException

Create a new ES940OSQVectorsScorer for the given IndexInput and explicit int4 disk format. The input should be unwrapped before calling this method. If the input is still a FilterIndexInput that does not implement MemorySegmentAccessInput or DirectAccessInput, an IllegalArgumentException is thrown. Non-wrapper inputs (e.g. ByteBuffersIndexInput) are accepted and use a heap-copy fallback.

Throws:

IOException

                                                        throws IOException

Create a new ES92Int7VectorsScorer for the given IndexInput. See newES940OSQVectorsScorer(org.apache.lucene.store.IndexInput, byte, byte, int, int, int, org.elasticsearch.simdvec.ES940OSQVectorsScorer.SymmetricInt4Encoding) for input type requirements.

Throws:
