None that I could find
rationale:
Most search implementations use some kind of reverse index or
keyword/document lookup table, often tied to a data file or RDBMS.
Vector searches are neat in that they represent each document as a
feature vector in a high-dimensional space, and calculate similarity
based on linear algebra. On a practical level, they make it easy to
keep the search engine in RAM (no disk or DB access except to
retrieve the actual results), and they allow for sophisticated 'find
similar' searches on one or more existing results. The module itself
will be simple (to accompany a Perl.com tutorial), but allow for
subclassing to enable sophisticated parsing, term weighting, etc.
