Rewriting the search engine

One of the comments we got from 2 different sources was that the search engine had a few errors on specific searches were both string and place type was used.

Furthermore we had some discussions whether some of the techniques used in the search so far was beneficial. This concerned the expansion of the geographical region searched and the use of aliasses, and decided to remove them.

This off course called for a rewrite of the search engine, and I decided to also restructure the database, so to better allow for multiple languages (an upcoming expansion for ZiTYZEN.dk).

Due to the restructuring of the database the number of files and tables that needed to be altered was roughly 50% and 10% respectively. I have had the guts to do this without SVN which I installed last month, and it wouldn't have been possible at all to do without a test-site.

Zummary: the result of the restructuring was very good, the search is performed faster and more correct, and the database is prepared for multiple languages. My advise: "Rewrite, restructure, and refactor as often as you can!"
