If your text file is constant, I guess that CDB_File is a possible solution if you have more diskspace than RAM. If you have a cluster of machines, most likely Cache::Memcached is a good solution, because it lets you keep the whole file (distributed) in RAM and search it relatively quickly.

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
