Add search method

As mentioned in #3522879: Support Elasticsearch Connector 8.x → this will result in a breaking change and should be done in a major release.
Why is this is breaking change? We should rename the current method to msearch to match the elastic documentation and the new method should use the current search method (but changed ofcourse).

Thanks tim-diels for working on improving this part. A new branch created 2.0.x

Hi mohamad, thanks for the quick response. Can you also add it as a (download) release (2.0.x) so we can tag the issues to the version? If you don't know what I'm talking about, just let me know. You can also ping me on slack at tim-diels

Hi @timdiels1,

Thank you for your work on this.
Could you please confirm the release of version 2.0.0 → ? Once confirmed, we’ll go ahead and close the ticket.
