Hi Zac,
this is the first time I've used these two and looks like both of them work like "with" (result "without" is the same as "with")

There is more.
Using "with" or "without" can hang the program and shortly after just close it.

To reproduce this you need special condition: upon start-up the search bar MUST have "with:XXX" or "without:XXX", where XXX is a property name.

Now follow the scenario:

• the program has started, let's say in the search bar we have: with:artist
• click on indexed folder - the serach box will change to location of that folder
• in the serach box type "with:genre" (or other property)
• press "enter"
• now, click with mouse on the search box - this is the moment when program freezes, the box cannot be clicked anymore

Thanks
