BASIC SEARCH

ADVANCED SEARCH
An advanced search allows for more flexibility with using keywords which can sometimes help find additional relevant search results if there are very few.

AND narrows the search and all words must be found in each source.
OR broadens the search and works well with searching synonyms or related words.
* finds singular, plural or other forms of a word.
