Search or filter games on field not matching a value

[fourier]

Is there an easy way to search for games having event 'not matching or including' a particular value? For example, my current filter is:

Date: 1970-2015
Length: 19 to 49
Results: 1-0, 0-1
Search filter selected

I want to add to this filter the following:
Event: not equals/containing 'Blitz'

(to exclude any Blitz events from the results)

I've tried using the 'Reverse filter' option to make this work, but can't seem to get the result I was expecting.

Thanks in advance.

Yes you can use ! in Quick Search. For example:
!Event:Blitz
