Keyword searches may use all lower-case letters. But the use of capital letters will search only for those capital letters. Words entered as a phrase will be searched as a phrase. Do not use quotation marks (unless the item being searched for also contains quotation marks). To find entries containing discretely different words, use "and", "or", and "not" between the words. If you cannot type in diacritical marks like “ñ” or “í”, use wildcards. For examples of usage click here.
