Alternte query plans

[Monika Shah]

db.explain() shows one winning plan and only few rejected plans. Are these only rejected plans?

[David Storch]

Hi Monika,

Yes, those are all the rejected plans generated by the server. There are no plans which are considered but not reported (except for the issue described by SERVER-19350).

Best,

Dave

 Thank you for clearing doubt. My next question is How can I trace source code during query execution?

Hi Monika,

It sounds like this is the same question as the one you've asked here: https://groups.google.com/forum/#!topic/mongodb-dev/rt55wBWs5yw. Let's keep the discussion on that other thread.

Best,

Dave
