Index API

Indices are used for fast nearest neighbor search. Optionally, they may also perform transformation prior to indexing.

The module provides a few index implementations:

• FaissIndex: Uses the Faiss library for fast nearest neighbor search.

• HnswlibIndex: Uses the hnswlib library for fast nearest neighbor search.

• PolarIndex: Transforms spatial coordinates into polar coordinates for indexing.

• WhiteningIndex: Whitens the data before indexing.
