This is the most powerful query refinement technique. Add a discriminating word or a phrase. Adding baseball makes the query less ambiguous. Capitalize when appropriate. For example, without capitalization, wired could refer to electrical cables and not Wired Magazine.
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.
