Changelog Entry

Description

Adding a feature- Basic Elasticsearch as a vector store support.

Added

Elasticsearch as a vector store support

Additional Information

Even though collections in ChromaDB can be easily translated to Elasticsearch indexes, it is bad practice to have many small indexes(might stress the cluster). therefor, I preferred using a different index only when using different embedding length, and save the collection ID as a field, which I filter by.
to summarize:

I use an index for each different doembedding vector length
Each index holds a "collection" field which is how you actually search a collection
