By default this searches for your words as an exact phrase across every chapter, including the full body text. Use the Match options or these operators to broaden or refine a query:

• Match: All of these words — finds chapters containing every word, in any order (e.g. justice virtue soul).
• Match: Any of these words — broadens further, so only one of the words need appear.
• "Quotation marks" — force an exact phrase even in another match mode (e.g. "the good life").
• Minus sign — excludes a word from results (e.g. justice -republic).
