Aggregate queries on MongoDB array elements -


how query mongodb array greater than($gt), less than($lt) queries? 

{{     "rank": 600,     "installs": [100-500],     "reviewers" : [         122, 233     ],     "category" : [         "sports"     ],     "url" : "https://play.google.com/store/apps/details?id=com.transylgamia.kingofspeed3dautoracing" } {     "rank": 900,     "installs": [100-500],     "reviewers" : [         50, 100, 200     ],     "category" : [         "sports"     ],     "url" : "https://play.google.com/store/apps/details?id=com.b2w.cricket_2014" }}

i want this:

db.col.find({rank: {$gt:500}, **reviewers.0**: {$gt:50}}, {_id:0, reviewers:1, category:1, url:1})

and first document because first element of array 1st document qualifies. tried different searches not able find help.

edit: changed integer.
