Search Help Information

Use the search box above to search all collections at once. Use Advanced Search to limit your search to one or several collections.

A simple keyword search returns results ordered by relevance. Searching on "ancient warfare" will prioritize records that contain the full string "ancient warfare", but will also include records that contain the individual words "ancient" or "warfare".

To fine-tune your search, use these characters at the beginning or end of words:

  • a leading plus sign + indicates that this word must be present in each item.

  • a leading minus sign - indicates that this word must not be present in the item.

  • an appended asterisk * serves as the truncation (or wildcard) operator.
    Words match if they begin with the word preceding the * operator.

  • a phrase that is enclosed within double quote characters " matches only items that contain the phrase literally.
