The 'gfind' command does a search through Chumash, Navi, or Kesuvim to find contiguous words which have the same gematria as the search string. Only the basic form of gematria is used for this process. [To investigate other forms of gematria calculations, please refer to the 'gematria' command on he Previews page.]
Input for the 'gfind' command can take the form of a single word, multiple words, numbers (positive or negative), or a mixture of words and numbers. Internally, the total of the gematria and any numbers is computed and the search gets underway.
As explained in the manual, one iteresting use of the gfind command is to uncover ideas for a D'var Torah at a Sheva Berachos. In response to the input of the Chosson's and Kallah's names, 22Lookup will display many gemara-equivalent strings. Weaving a story around a subset makes for an interesting derasha.
