Add a discriminating word or a phrase. As before, the before query is ambiguous. Adding events makes the query less ambiguous. Capitalize when appropriate. For example, without capitalization, market bulletin could refer to notices about stores and not Agriculture's Market Bulletin.
Capitalization reduces the ambiguity.
Be sure to place a comma between unrelated capitalized words, since the search engine 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.
