we need this feature, @dartpain could you please help to review it?

So few comments on this PR,

1. I added filter parameter to search method
2. Lots of upgrades to make it all work
3. Dont use Milvus here as local file - its recommended to deploy it separately, as worker and backend containers will query it.

Finally to install in just add langchain-milvus==0.1.4 to your requirements txt file
