Puggle is a desktop search engine that provides full text search over files, folders, music, photos, Web pages, and other data that are stored locally on your computer. Puggle is able to create many different indices, each with a different configuration. For example, you may have a different index for your music collection as well as your documents. Each of them can be used on demand, simply by loading it. Furthermore, Puggle supports indexing of portable devices, like USB flash drives or external hard disks. The index will be stored in the device, using relative paths, allowing you to search over the data very quickly on any computer.
