Struct VectorSparseInvertedIndexMethod 

pub struct VectorSparseInvertedIndexMethod;

Simple inverted index for sparse vectors

CREATE INDEX t_idx ON t USING toy_vector_sparse_ivf (embedding)

It accept single column which must contain vector encoded in sparse format (e.g. vector32_sparse(…)) It can handle jaccard similarity scoring queries like the following:

SELECT vector_distance_jaccard(embedding, ?) as d FROM t ORDER BY d LIMIT ?
