 `is` and `isNot` are single-selection operators, while `isAny`, `isNone`, `isAll`, and `isNotALl` are multi-selection. By default, a filter with no operators declared will support the `isAny` and `isNone` multi-selection operators. A filter cannot mix single-selection & multi-selection operators; if a single-selection operator is present in the list of valid operators, the multi-selection ones will be discarded and the filter won't allow selecting more than one item.
