Unity Books Lens PPA installation instructions

One of Unity's main features is the Dash. The Dash allows the user to quickly search for information both locally (installed applications, recent files, bookmarks, etc) and remotely (Twitter, Google Docs, etc).

The Dash achieves this by having one or more Lenses that each are responsible for providing one category of search results for the Dash. The user may search the Lens either through the Dash home screen (called global search) or through the Lens' own page in the Dash by clicking on the Lens' icon on the Lens Bar.

On it's own, a Lens is not very useful. It can guarantee an icon on the Lens Bar and a page in a the Dash but nothing will happen when the user searches it. This is because a Lens does not actually perform any searches itself. Instead, a Lens will have one or more Scopes which are the actual engines that do the searching for it.

This means that it is possible for new Scopes to supplement results of existing Lenses i.e. a Google Docs Scope can supplement the results of the default Zeitgeist Scope in the Files Lens, with results appearing side-by-side. Also, this means it is now possible for one Lens to have many Scopes i.e. the Music Lens can have a Banshee, UPNP and Spotify Scopes providing results to it.
