Description

A query needs to have at least view, constraints and constraintLogic. The view is a vector containing the columns of the query output. The constraint is a matrix containing the following columns: path (the path of the constraint), op (the constraint operator, one of '=', '!=', 'LOOKUP', 'ONE OF', 'NONE OF', '>', '<', '>=', '<=', 'LIKE'), value (the constraint value), code (the name of the constraint), extraValue (optional, required for LOOKUP constraints). The constraintLogic by default is "AND" operation, e.g., "A and B", where A and B are the codes in the constraints.
