Match word or phrase exactly
Searches for the whole string of characters, including spaces, in the order in which they appear in the Search box. For example, if you type “DocuCom PDF,” the result lists only instances of “DocuCom PDF” and not “DocuCom” or “PDF DocuCom.”

Match any of the words
Searches for any instances that contain at least one of the words you type into the Search box. For example, if you type “at all,” the results include any instances in which one or both of the two words appear: at, all, at all, or all at.

Match all of the words
Searches for instances that contain all the words you type into the Search box, but not necessarily in the same order. For example, if you type “at all,” the results include instances of “at all” and “all at.”

Boolean Query
Searches for terms or phrases you indicate using Boolean operations. Boolean Query is only available for multiple-document searches. See Using a Boolean Query in Multi-document Searches.
