Search::InvertedIndex is a general purpose inverted indexing system suitable for medium scale searching. The compiled external modules used are Digest::SHA1 (needed because it uses the 'Tie::FileLRUCache' module for performance enhancment on searches) and DB_File (because it used by the 'Tie::DB_File::SplitHash' module). The module itself is Perl with the two exceptions noted above. If you have 'Digest::SHA1' and 'DB_File' on your system, no compilation is required. This module is the core needed to build medium scale search engines. |
