On every single type of list you can generate using Formulists, there is an options tab to filter by location, bio and followers.  Here are the steps on how to work it:

1.       Go to the tab that says “Profile Filter Options” either right when you first make a new list or when you are editing an existing one.

2.       Filter by one, two or all three of the filters- location, bio or followers.

3.       You can enter in multiple words to filter by and use the same type of advanced operators used in google search (“and”, “or”, “-“ or “”.

and    => include all words that have “and” in between them  

or       => include at least one of the words that have “or” in between them

-         => exclude the word that comes after the “-“

””       => keep only the exact words in that exact order without any change
