BerkeleyDB, you've got exactly one index per file. You could fake extra indexes, but you'll have come up with "one to many" relationships - you may find "chevy" in the "brands" index, but it can't refer to any single other record - it has to refer to multiple other records - which is ok with a RDBMS, but a pain with .db files. If you make a linear search through the .db file every time, performance should be ok for no more then a hit a second, but will be slower then doing a linear search through a flat file. With a hashed file, you access the records randomly when you do a "linear" search, but with a flat file, a linear search really is linear. I wouldn't have any reservations at all about doing... EACHREC: foreach my $rec (keys %tiedhash) { foreach my $criteria (split / /, @searchkeys) { next EACHREC unless $rec =~ m/$criteria/; } print qq{
  • $rec $tiedhash{$rec}\n}; } or something thereabouts...
