Db.user_profile.find ({$where: "this.disk_rack.length > 1"}), but this js engine executes very slowly

A better way is CreateextrafieldNamesArrayLength, update it with names array length and then use in queries:db.accommodations.find ({"NamesArrayLength": {$gt: 1}})

It will be better solution, and will work much faster (you can create index on it).
