default search parameters

[musicnerd]

Currently searches give redundancies in the results which could be prevented if we made "piece" the default search parameter. For example, it will list both the "piece" (which has movements), and each individual movement of that piece as separate (redundant) results. It is duly noted that when the user attempts to "download all" those redundancies ARE removed so that they do not download the redundant files multiple times. However, it is misleading in the search results to say there are 18 results when there may only be three pieces which each have 5 movements. Savvy?
(It is also duly noted that a user can filter results to just "piece" but I'm not sure that would be immediately clear to a new user.)
