Tools: Twitter - Follow Resource | Follow people by keyword search


I am trying to use the tool for twitter which will allow me to search for people by keyword. I have entered keywords both with hashtags and without hashtags separating each keyword with ‘,’. the problem I am experiencing is when I click extract users only one of the entered keywords is searched and results extracted. When I change the selection ranking a different keyword is searched only. Is anyone else experiencing this issue? Am I doing something wrong? Is it possible to search more than one keyword at a time as a resource for following users by keyword on twitter?
