We should allow queries such as

a: { $near: ..., $within: ... }

, but geonear predicates cannot be combined with other predicates in the same field, so we have to do for example,

$and: [ { a: { $near:... } }, { a: { $within: ... } } ]

. Also, ordering shouldn't matter.

In addition, for legacy formats for geonear queries, currently ordering matters and is incorrect in that for example,

a: { $eq: ..., $near: ..., $maxDistance: ... }

would error, but

a: { $near: ..., $eq: ..., $maxDistance: ... }

would ignore the $eq.

depends on

SERVER-19713 verify() failure when specifying $minDistance or $maxDistance without geoNear operator

duplicates

SERVER-22206 $near query operator should validate its arguments

SERVER-17234 geoNear command should return error for invalid arguments
