What are these numbers in Goto Anything of Sublime Text 2

Question

I've googled a lot but unfortunately I can't find out what these numbers aside the file names means when you Ctrl+P (Goto Anything) in Sublime Text 2.

Ideas?

Answer 1

According to hearsay:

• Indicator of how likely your input is meant to describe that file.
• Increases with match quality. Typing in "application" in your screenshot should yield significantly higher numbers.
• Increases with the popularity of the file. As a result, it will display the busiest file first if there are multiple matches.
