For more complex searches, use the ampersand (&) to require that more than one term be in the document, or the pipe ( | ) to have either of more than one term. Use the exclamation point ( ! ) to exclude words following the exclamation point.

Examples:

banding & creamer's = all pages with both words
banding | creamer's = all pages with either word
banding ! creamer's = all pages with the word banding, excluding those with the word creamer's
