The main page for this idea is Summer Coding 2010 ideas - Gnome - Nautilus search.
Summary of idea: Nautilus is the default file manager for Gnome desktop. The current state of the search dialog is suboptimal, our goal is to make it more rich and provide more options. For example, when we had set Tracker as the primary search engine, we also committed users to use their fulltext search by default. An option switching between filename-based matching and fulltext search would be great addition. Additional filters would also be a great asset.
