Some functions don't seem to work when placed in filter

[vsub]

Or maybe I am not doing it the right way...or maybe a bug
For example if I create a new filter and in the search I type a function
Those work:
runcount:>=0 - this is what I use on the "Everything" filter to see the files I open(there was some reason for choosing 0 but I don't remember what)
video:|audio:|pic: - filter to display all media files specified in the filters for those media types
!folder: - filter to display only files
folder: - filter to display only folders

Not work:
infolder:
parent:
There may be more but the point of the thread was those two

If I set them in filter and type some full path(C:\Windows\System32\),everything displays nothing but if I switch to any other filter and type infolder: or parent: in front of the path,then all filters work

Something like this?

So this is how it works.

That's because the parent: function requires a parameter ( myquery in the filter definition).
runcount:>=0 or audio: don't need that extra parameter.
