Expanders let you broaden the scope of your search. They do this by widening your search to include words related to your keywords or including the actual text of the full text results in your search.
Common expanders that can appear below the Refine Search sub-tab include:
Also Search for related words - Select this option to expand results to include the synonyms and plurals of your terms.
Search within full text articles - Select this option to search for your keywords within the full text of articles, as well as abstract and citation information. This applies only to words not qualified by a field code.
Include all search terms by default - Select this option to search for all terms you entered, in any order within the text. Your terms are automatically "anded" together. If you surround terms with quotation marks, the phrase within the quotation marks is treated as one term.
In the Find field, enter your search terms.
Select the expander you want to use from the Expand Your Search section of the Refine Search sub-tab.
Click Search. The Result List appears.
