Support conditional Operator AND/OR

[Jerkz08]

hello, I love the component but I'm lacking some feature like:

1. support of conditional operator AND/OR
2. I notice it has maximum of 3 sequence to complete encapsulation (field + operator + value). It would be nice if can customize to four (4) sequence (conditional + field + operator + value).

AND/OR operators can be realized using duplicate filters. But definitely this needs to be addressed properly.
Thanks for the feature request.
We will try to implement it in coming days.
