Google is continuing to push the search engine forward and, as a result, the unification of its products. The latest mating sees Google searches including results from a user's Gmail e-mail. However, not everyone will get these results right now as it is only being offered as an exclusive "field trial."

Users can request to be in the field trial on Google's website, although participation is not guaranteed. This change is almost a natural extension for Google. "Gmail is almost larger than our web corpus and it continues to grow." says Kamdar. The change is part of Google's on-going mission to build the search engine of the future.

The Gmail results won't be listed like the rest of the results. Instead, they will appear on the right-hand side like the new knowledge graph results do. Google will be able to parse out what an e-mail is, be it a shipping order, flight confirmation, or something else altogether, and this will help it provide better results.
