How Search Works
By default, searching for multiple words will return results containing any of the words you entered. For example, searching cancel reservation will find calls that mention "cancel" or "reservation" (or both).
Match All Keywords - When checked, results must contain every word you entered, but the words don't need to appear next to each other or in any particular order. Searching cancel reservation will only return calls where both "cancel" and "reservation" appear somewhere in the conversation.
Exact Phrase - When checked, results must contain the exact words you entered, in the exact order you typed them. Searching cancel reservation will only return calls where the phrase "cancel reservation" appears word-for-word in the conversation.
