Hello,
until a few days ago, I thought that hl only refers to the language in which google displays the results, but errare humanun est.

eg:
http://72.14.207.104/search?q=redscowl%20bluesingsky&hl=es
http://72.14.207.104/search?q=redscowl%20bluesingsky&hl=en
http://72.14.207.104/search?q=redscowl%20bluesingsky&hl=pl
shows pretty different results.

Does somebody know, why?

I searched the google hp and googleed to try to find an answer but without success.

Thanks in advance.
Thomas
