Represents a filtering mechanism where the elements within each inner array are logically ORed, and the resulting arrays are ANDed together at the top level. Each inner array consists of objects with two properties: traitType (a string) and value (a string). For example: [[{"traitType":"trait1", "value":"value1"},{"traitType":"trait1", "value":"value2"}]] would return tokens that have "value1" OR "value2" for "trait1".
