title: cts:collection-match() with a more complex pattern?
body: <p>I currently have collection names with various patterns. In one of these patterns, the collection name ends in a date string, like <strong>2017-02-28</strong>. IS there any way to use <code>cts:collection-match()</code> or something else to select only the collection names that end in this format, i.e. <code>\d\d\d\d-\d\d-\d\d</code>?</p>
