Spotlight + Loro

I've been working for the past few hours to integrate the Spotlight index with Loro so that you can search for files by meta data attributes such as; artist, album etc and the basic functionality is working well - Spotlight can be accessed by adding the keyword 'Search' and then the criteria as you can see in the picture. It's still a bit slow but it's a very useful feature and necessary to make Loro central as a file browser. I'm going to improve upon the default Spotlight experience by allowing powerful operators such as AND and OR to be used.
