- The (optional) args string should be one of 'all', 'solved', or
- 'unsolved' to indicate which set of puzzles should be
- displayed. If omitted, this command will default to showing only
- unsolved puzzles.
+ The (optional) args string can be used to filter which puzzles to
+ display. The first word can be one of 'all', 'unsolved', or
+ 'solved' and can be used to display only puzzles with the given
+ status. Any remaining text in the args string will be interpreted
+ as search terms. These will be split into separate terms on space
+ characters, (though quotation marks can be used to include a space
+ character in a term). All terms must match on a puzzle in order
+ for that puzzle to be included. But a puzzle will be considered to
+ match if any of the puzzle title, round title, puzzle URL, or
+ puzzle solution match. Matching will be performed without regard
+ to case sensitivity and the search terms can include regular
+ expression syntax.
