Here's a patch for tracker-search-tool that allows the user to
explicitly search certain metadata keys, ala Google.
For example, searching for "album:Global" will just search for
Audio:Album tags, instead of everything, for 'Global'. Currently, the
seach is case sensitive (any way to make rdf seraches
case-insensitive?).
This patch includes support for key:
title --> DC:Title (this isn't working for Audio:Title)
format --> DC:Format
creator --> DC:Creator
keywords --> DC:Keywords
mime --> File:Mime (this isn't working, while `format` does)
path --> File:Path
ext --> File:Ext
artist --> Audio:Artist
album --> Audio:Album
track --> Audio:Title
subject --> Doc:Subject
author --> Doc:Author
