<p>The query creator is used to create and edit automatic playlists.
It is only capable of constructing queries that consist of a flat
list of criteria. It cannot nested criteria or represent full
boolean logic expressions.</p>
<p>In addition to query criteria, the query creator also allows the user
to specify limits on the size of the result set, in terms of the number
of entries, the total duration, or the total file size; and also the
order in which the results are to be sorted.</p>
<p>The structure of the query creator is defined in the builder file
create-playlist.ui.</p>
