The 'find' command (also known as the 'prog' command)
 allows you to search the database for a specified pattern.

 The usage is:

    find <expression>

 where the interpretation of <expression> depends on the
 current value of the 'search' variable. Searches may be
 performed in a number of different ways. See the help
 section on the 'search' variable for a full explanation.

 The output of find can be sorted in different ways,
 depending on the value of the 'sortby' variable. See help
 for the 'sortby' variable for a full explanation.

 The output format of the results can be changed through
 use of the "output_format" variable.

 The search criteria can be further specified to be restricted
 on domain names and pathname components. See the "domains"
 comand and the "match_domain" and "match_path" variables.
