Keywords may be separated by AND and/or OR statements for greater control of the search results.
For example, Microsoft AND mouse would return results that contain both words.
However, for mouse OR keyboard, the results returned would contain both or either words.

Exact matches can be found by enclosing the keywords in double-quotes.
For example, "notebook computer" would return results containing the exact string.

Parentheses may also be used for even finer control of results.
For example, Microsoft AND (keyboard OR mouse OR "visual basic").
