Sorry I completely dropped the ball on this one! Reviewing now

This looks super solid! Only a few minor things left, and also, could you please add a test in the handler? :)

I'm not sure what the problem is - maybe I misunderstood it - but it seems that the member parameter is propagated properly in the SDK? Maybe you could lay out the problem again in one comment, I think I must have missed something.

@aeneasr ready for review again. A note on the filter method, if someone passing regex query in the filter params then they are treated as exact. This can be changed in future PR. Let's try to close this soon.
