SWISH::HiLiter
SWISH::HiLiter marries Search::Tools and SWISH::API, basically providing all the tokenization parameters to the Search::Tools::QueryParser based on values in the Swish-e index header.
Version 0.05 is a complete rewrite to use Search::Tools (which was, in fact, originally derived in part from SWISH::HiLiter?).
