Taylor-Realtors is a Montana Real Estate Firm. The site features fast keyword and advanced searching using the Sphinx Engine with Thinking-Sphinx and multiple MLS feeds. One of challenges I faced during development was parsing the many types of files given to us through MLS providers because they don't all use the same format and they only provide images for the last couple days of listings so all the rest on initial import have to be found via sorting through hundreds of GB's of archived images. Nothing a fast computer, rake tasks, and mapping hashes can't fix though.
