  • By default, the search engine tries to locate records which match as much as possible all of the words entered in your search query

Opt to sort your results by Publication Year, Subject Category or Document Type

Use the following boolean operators in your search: AND, OR, NOT, TO.
For Example:

  • AND - Narrow search and retrieve records containing all of the words it separates
  • OR - Broaden search and retrieve records containing any of the words it separates
  • NOT - Narrow search and retrieve records that do not contain the term following it
  • TO - Narrow search by specifying a range of dates. The first date goes in the first text box, and the second date goes in the second textbox

Decide which fields to search for your keywords. Leaving it at the default "Anywhere in Record" is the most recommended setting.
