Description
When adding more than one filters for the same "column" (e.g. Status), the logical operator that will be used to combine them is always "OR", and cannot be changed by the user.
When setting two filters with "is" condition, leading to "is a or is b", the resulting predicate works fine.
But! When setting the filters with "is not" condition, leading to obviously malformed "is not a OR is not b", the resulting predicate cancels the filters effect!
For this reason and a lot more reasons that can came up to mind by just brainstorming, being able to further customize other aspects of the advanced search predicate is pivotal.
Please consider at least a "AND/OR" drop down menu for the logical operators.
