How to get one keyword's priority in itunes?

I see many ASO(App Store Optimization) websites give one parameter , keyword priority.


The request like this: https://search.itunes.apple.com/WebObjects/MZSearchHints.woa/wa/hints?clientApplication=Software&e=true&media=software&term=facebook


The response like this:

<dict>

<key>term</key>

<string>facebook</string>

<key>priority</key>

<integer>10743</integer>

<key>url</key>

</dict>


Facebook's priority is 10743 , it means facebook's rank is very high in ios itunes , I want to know how to get the priority , I need the api document , I have searched the answer for 2 weeks , if you know something about it , plz tell me , thank you very very much
