Google recently rolled out new search features that allow users to crawl their Gmail inbox with parameters such as [my hotel reservation], [my restaurant reservation], and [my events].

This comes in addition to the [my flights] query that currently allows users to find their flights through via the desktop, iOS and Android. Basically, this brings some of the excellent Google Now functionality to the Web.

The new features are only available for those in the U.S. (and in English) for now, and Google Apps aren't eligible for the functionality, TechCrunch said. The search experiments are getting more robust and detailed, though whether you want to be tracked so thoroughly is up to you. You can learn more about Google's search experiments here.
