In the Qualys GUI (Vulnerability Management -> Assets -> Asset Groups -> Search), you can enter a title of "foobar" and it will use that phrase as a substring search (i.e. return results for "foobar", "foobar_group1", "another_foobar_group", etc.)
However in the API, I can only find a way to do exact-title-match searching. That is, posting to /api/2.0/fo/asset/group/ using "title=foobar" will return only a group named "foobar", not any of the others listed above.
Is there a way to do Asset Group title substring searching with the API?
