This option creates a new named query that marks all tests that would have been marked by running each query, one after the other, while retaining existing marks. Since Mark by Named Query clears existing marks before running a query, the only way to achieve this result is to create a new query that combines the queries by union.
Click to combine two or more queries by intersection. This option creates a new named query that marks every test that has the criteria specified in all constituent queries. Use care when combining queries by intersection.
