mongoQuery.addToQuery(['field1', 'field11'], mongoQB.$ne("-1")) // adds field11 under field1 with {$ne: "-1"} value

mongoQuery.removeFromQuery(['field1']) // removes field1 along with its child field1 from the query

mongoQuery.sort("field1.field11", 1) // applies sort by asc on the child field11

mongoQuery.removeFromQuery(['field1']) // removes field1 along with its child field1 from the query
