Approximate Search
Similarity searches in Postgresql using metric spaces

A way to realize similarity searches between objects as words, sounds, images, etc.. using metric spaces. It is a way to do range queries, nearest neighboor queries and K-nearest neighboor queries.
Includes coverage of the "Edit Distance" contrib module for PostgreSQL, as well as external indexing in C, and ongoing work to construct a special index type for similarity search.
