19 A few notes:
20 * The matching is case-insensitive, so if zuff matches, so will ZUFF, zuFF, and any other variations in capitalization.
21 * Some characters have special meaning in a regular expression, so to match those characters specifically, they must be "escaped" with a backslash (). As you can see in the above example, \[ and \] are such characters. (Others include ".", "?", and "*"). The backslash is also used for other things (I wasn't kidding about regular expressions being complex: consult other documentation for details about other uses of the backslash character), but this is the most likely use in a topic expression.
