There are three great tricks that will work in most databases, as well as Google: Boolean, phrases, and wildcards.
Boolean operators allow you to narrow or expand your search results by connecting search terms together. There are three boolean operators: AND, OR, & NOT. AND will narrow your search by requiring results to have both terms. OR will expand your results to include both of your search terms. NOT will exclude results that have the second term from showing in your search. When using boolean operators in ONESearch, be sure to type them all in capitals as shown above.
You can search for phrases by typing quotation marks around the phrase, e.g., "black lives matter"
You can search for variations on a term by using wildcards. In ONESearch:
? - Enter a question mark to perform a single character wildcard search. For example, type wom?n to search for records that contain the words woman, women, and so forth.
* - Enter an asterisk to perform a multiple character wildcard search. You can use this trick to search for terms that may appear with different endings, suffixes, or tenses. For example, type cultur* to search for records that contain the words culture, cultural, or culturally.
