Use Lucene's MultiLeafCollector to speed up concurrent-segment exact search

3

Lucene introduced [MultiLeafCollector](https://github.com/apache/lucene/blob/main/lucene/core/src/java/org/apache/lucene/search/knn/MultiLeafKnnCollector.java) to optimize concurrent segment search. While this cannot be used for faiss due to JNI layer, this can possibly be leveraged for exact search. This can further...

Adds search implementation of context aware segments

9

The implementation aims at pruning search space based on context awareness when context-aware-grouping mapper is presents. It does a best attempt extraction of grouping criteria from the query, if no...

Determine Max distance computation threshold for hamming distance

1

When using efficient filtering, estimated distance computations are compared with max distance computation threshold to determine whether to use exact search or approximate nearest neighbor search. The Max distance computation...
