Nine new options range from date and time specific searches, to filters for shopping web sites.
"Today we're announcing nine new Search Options tools: past hour, specific date range, more shopping sites, fewer shopping sites, visited pages, not yet visited, books, blogs and news," explained Google product manager Nundu Janakiram in a blog post.
"These features have been rolling out gradually and will be available globally in English by the end of the day. You can try them yourself by searching Google and clicking 'Show options' in the blue bar just under the logo."
Google added search results from forum and discussion posts earlier this week, and has now added the option to search within its Books, Blogs, and News pages. This will make the business of performing research quicker, easier and more accurate, the firm said.
The new time and date options let users search for the most recent posts, or any results found within a specific date range, both of which Google claims will be useful for people working on research projects.
The 'visited pages' feature can filter out results from a user's visited sites, while adding the option to search only for sites that have not been visited before, giving users the chance to find some previously missed, but relevant pages. The feature requires a Google Account and the web history option enabled.
