Hi,   I am new to Alfred. I have a small question. I want to search inside documents of a certain file type. I have used the "in" prefix which seems to work, but it does not work along with file filter i created. For example, my filter is extension .gaml which is basically a text file with that extension to suit as a input to a particular open source software.    While this file filter works, I am unable to use then use the "in" prefix to search inside this gaml files.
