Document Search Tips

By default, a search looks for all of the words you enter, within all available search fields.

Enclose terms in quotes to search for a specific, multi-word phrase: e.g., "Robert Smith"

Use Boolean search operators such as AND and OR with parentheses, and use NOT to exclude terms from your results. For example (Nixon AND mao) OR NOT Kissinger. (Note that you may not start a query with a NOT operator).

You may also use * for "wildcard" searches, so a search of J* Brown will match both "Jerry Brown" and "John Brown".
