Limiters help you focus your search by filtering results based on specific criteria, such as publication date, subject, etc. After running a basic search, you’ll find these filtering tools in the “Refine Your Results” section located on the left side of the screen (see below).
Make sure to scroll through all the options, as some valuable limiters (like Language) may not be visible right away.
To access the complete list of options for limits, click on the “Advanced Search” link to the right of the search box at the top of the page.
