The keyword search looks for a keyword or phrase exactly as typed. It will search all fields in the database for the term you enter. Do not use multiple keywords unless they are likely to appear together in the way you specify.

Avoid using plurals, as the singular form of a word will find singular and plural occurrences, e.g. searching for "wine" will find all instances of both "wine" and "wines", whereas a search for "wines" will omit all instances of "wine" (singular).
