Search Basics

To get started, you can enter any phrases in the search box, for example "sleep disorder".

By default, the search will perform on publications containing both "sleep" and "disorder" words. To expand your search for publications with any of the words, add "OR" operator between the words. For example, "sleep OR disorder".

To exclude certain word, use "NOT" operator, for example, "sleep NOT disorder" will search for publications with "sleep", but not "disorder".

You can also use Advanced Search to build you query with the operators.
