2.month message was created.
3.gender of person.

5. name of tag attached to message.

Considering only those groups where number of messages greater than 100.

You can't do joins in elasticsearch.

So the question is less about the query but more about the modelling of your data.

For example, it seems that what you want to search for are messages. In that case index messages.
And you need the author name of the message to search? Then add the author name in the message object.
