Keywords may be separated by AND and/or OR statements for greater control of the search results.

For example, Science Fiction AND Fantasy would always contain both words. However, Science Fiction OR Fantasy could contain both or either.

Exact matches can be searched for by enclosing keywords in double-quotes.

For example, "A Christmas Carol" would generate results that match the exact quote.

Parentheses can be used for further control.

For example, "All things" and ("bright and beautiful" or "wise and wonderful").
