I'm trying to update a site that has a huge amount of content on it, referenced
by URLs with a unique number for each item. A typical URL might look like
this:

<http://www.domain.com/category/item_23456/>

The site is created dynamically, so I need to find a way to retrieve only
pages that are new since the last update by saying something like:

fetch pages with path containing 'item_' + (number > 23456) + '/')

Is this possible with the current version (3.33)?
Cheers,

Steve
