language search in gmail

A reader of Googling Google found a hidden feature in Gmail that allows the users to search messages by the language they are written in. Just type in language: follow with name of the language (e.g. English, French, Chinese).

Although many praise Gmail for its search ability, I rarely use it, because 1) most emails I receive everyday are “<something> of the day/week/month” which I delete immediately after reading them, and 2) the first page of my inbox, which displays 25 conversations, already showing all the (important) emails I receive for the last 30 days.

Yet there are like 10 of them I need to reply to. Well, I been busy. (not a very good excuse, I know) :P
