How to filter Google search results by date?

This is actually helpful when you want to search for software information about the current version or about a particular older version. While on a Google search results page, click Tools (Search tools in a phone or tablet) and choose a time frame from the Any time dropdown box that appears.

Alternatively, when you want to look for information that has been published before or after a particular year, you can do so by using adding your search term with before:<year> or after:<year>.
