Allow query field to be passed in ElasticKnnSearch.knnSearch

[jeffvestal]

System Info

The _default_knn_query takes field arg to specify the field to use when performing knn and hybrid search.

both knn_search and hybrid_search need to allow that to be passed in as an arg and pass it to _default_knn_query

I'll make the update

Hi, @jeffvestal! I'm Dosu, and I'm here to help the LangChain team manage their backlog. I wanted to let you know that we are marking this issue as stale.

From what I understand, you opened this issue requesting the ability to pass a query_field argument to the knn_search and hybrid_search functions in order to search over a different field name other than the default vector. However, there hasn't been any further activity or comments on this issue since you opened it.

Before we close this issue, we wanted to check with you if it is still relevant to the latest version of the LangChain repository. If it is, please let us know by commenting on the issue. Otherwise, feel free to close the issue yourself or it will be automatically closed in 7 days.

Thank you for your understanding and contribution to the LangChain project!
