Search keywords may be separated by AND and/or OR statements for more refined search results. For example, Microsoft AND mouse would return results that contain both words. However, using Microsoft OR mouse would return results containing either or both words.
Search results can be limited to exact matches by enclosing the keywords in double-quotes. For example, "notebook computer" would return results containing the exact phrase.
Parentheses may also be used for for maximum refinement. For example, Microsoft AND (keyboard OR mouse OR "visual basic").
