As before, the before query is ambiguous. Adding ontario makes the query less ambiguous. Capitalize when appropriate. These examples, when all lower case, have a variety of possible interpretations. For example, without capitalization, rock gardens could refer to rock garden design and not Rock Gardens found at the Royal Botanical Gardens.
Capitalization reduces the ambiguity.
Be sure to place a comma between unrelated capitalized words, since Infoseek treats adjacent capitalized words as if they formed a single phrase. It is always a good idea to capitalize proper names. The after version above does both. Use a field specifier. See Special Searches for more information on field specifiers.
