Not me ... this is ancient lore e.g. Knuth vol 3 of TAOCP 1973 edition page 391 "If we make two copies of the file, one in which the keys are in normal alphabetic order and another in which they are ordered from right to left (as if the words were spelled backwards), a misspelled word will probably agree up to half or more of its length with an entry in one of those two files." _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
