Often you retrieve more relevant results with a complex search that includes your key concepts and their synonyms.
Combined Search (Parentheses)
Use parentheses to group Boolean statements.
First, put the synonyms for each concept in brackets with the word “OR” between them. Then, connect the key concepts with the word “AND”. Here is an example: “(television or tv) AND child$”. Below is the first screen of results for this search query. Note that records with EITHER the word tv or the word television are retrieved, as long as the word stem child$ also appears in the record.
Advanced Search Screen:
Search using AND, OR and wildcards. Synonyms are enclosed in parentheses and connected by AND.
