Dear daoquanghungGTVT,

Google result ranking is a cryptic business critical (for Google) algorithm 
that takes in to account the user profile and also depends on your location and 
servers and what not etc. - you can find more about google ranking system by 
googling it.

Anyway this is not a valid bug report for Robot Framework.

Hi Mikko,

 Thank for your care. Just make this issue clearly.

Because using Web_RF(Web opened by Robot Framework) and non-Web_RF(Web opened 
by natural browser) at same location and same keyword? but the result is 
different 

I don't think this issue relating to Google ranking method of GOOGLE. Would you 
like to  explain more than.

Thanks,
Hung.

Selenium uses a different user profile than what you are using.

On my machine the result will vary depending on browser and profile from 5-8th.

This is not a bug in Robot Framework - what you are experiencing is a very 
intelligent feature of google search engine. 
Robot Framework doesn't itself know anything about browsers or web testing - it 
uses other tools (Selenium2Library that uses internally Selenium) to connect to 
the browser.
What you are seeing are the results from a server of Google - this is not in 
anyway dependent on Robot Framework.
If you want more information than I suggest that you contact someone from 
Google.
