Google has added a few new filters to the search options panel it introduced last May, emphasizing speed and continuity on its search results pages.

The "show options" link at the top of a Google search results page brings up a number of filters on the left side of the search results page that allow searchers to refine their queries, allowing them to search just for content types like videos or search results from a certain timeline. Google is gradually rolling out some new options in that panel, allowing searchers to find results from the last hour or results posted in Google Books or Google News, said Nundu Janakiram, product manager in search. Searchers will also be able to select if they want to see more results from stores or less results, depending on whether you're shopping or looking for other kinds of information.

You've obviously been able to search within Google News or Google Books up until this point, but Google thinks the new search options are useful because they won't require the searcher to leave the main search results page. Clicking on the "News" filter will present Google News result, but the look and feel of the page won't change with the new filters, Janakiram said.
