Size parameter for Autosearch?

[Exile82]

Hi guys! Despite I am a long time user, this will be my first post here. Thanks for excellent software, I use it every day, but recently I have started to use the autosearch more and more. But I still miss a size parameter, like you have in the ordinary search feature (well, I do not use that specifically, since I sort my search result by size). Or is it possible to add that parameter in the search string under advanced tab?
