Create filter to search for an element in an array

[regniblod]

The current implementation for contains and not contains does not covers the case where a property is an array. It performs a simple LIKE '%{value}%', which does not actually checks if the element exists, just that this word is in the serialized string in the database.

Example Database value: Apples,Apple Macbook,Apple iPad Element searching for: Apple

Expected result: No element found. Actual result: Matches the array.

I know there's no easy way to fix this and most likely it will be a BC, but I'm opening this issue as a reminder of a cool-to-have feature.
