问题
Are there any ressources on what the parameters in a Google query mean? Any analysis how the Google search pages work internally?
Examples would be
http://www.google.com/#hl=en&source=hp&q=lol&aq=f&aqi=&aql=&oq=&fp=45675624562456
or
http://www.google.com/url?sa=t&source=web&ct=res&cd=11&ved=KJSGHFKSDJF&url=sfdgagasdgasdgasgasg&rct=j&q=fghthwrteghedgf&ei=asdfasdfsa&usg=asdfasdfasf
回答1:
- q=searchstring is the search string
- source=something is where the search originated (www.google.com webpage, Google Toolbar, Quick Search of various browsers)
- ie=utf8 input encoding
- oe=utf8 output encoding
- rls=en ?interface language?

&gws_rd=cr is related to redirects too countries. For example if you wanted to get to google.com in UK you need to append that parameter, if not you get redirected to google.co.uk
