Description

There's no search integration (e.g. queries) for the current vector values, no documentation/examples that I can find.

Instead the codec has this method:

TopDocs search(String field, float[] target, int k, int fanout)

First, the "fanout" parameter needs to go, this is specific to HNSW impl, get it out of here.
Second, How am I supposed to skip over deleted documents? How can I use filters? How should i search across multiple segments?
