OQueryOperator
Query that should be executed can be presented like: [[property0 = keyParam0] and [property1 = keyParam1] and] propertyN operator keyParamN.
It is supped that index which passed in as parameter is used to index properties listed above and responsibility of given method execute query using given parameters.
Multiple parameters are passed in to implement composite indexes support.
