Feature request

Seems fuzzy full-text search cannot be configured from the API (please correct and help me if I am wrong). Using langchain-mongodb package. I was editing the source to get it running:

•                     }},
         }
     }
  

  ]

This is using the defaults from the MongoDB API.

We should make the fields become configurable from langchain.

Motivation

Getting more out of the langchain/mongodb integration.
