Feature request

can we parametrize the max_length value for text field in Milvus?
See here:
https://github.com/langchain-ai/langchain/blob/395674d5037756bef25d7fa8da93525874bb5cb8/libs/community/langchain_community/vectorstores/milvus.py#L354C72-L354C78

Motivation

I understand the limit has to do with the DB performance etc, but texts can be longer than that and chunking is not necessarily an option

Proposal (If applicable)

Set an argument in init (and in .from_documents() ideally) to set the max length for the text field. I. believe it will be rare to have some metadata field longer than 65,535 chars.
