+
+PieCrust returns _iterator objects_ as template data in several cases:
+`pagination.posts`, `assets`, `site.pages`, etc. Any time there's a list of
+_stuff_, you can bet it's returned as an _iterator object_.
+
+At first glance, there's not much difference with a simple list:
+
+{%highlight 'django'%}
+{%raw%}
+{% for page in site.pages %}
+* [{{page.title}}]({{page.url}})
+{% endfor %}
+{%endraw%}
+{%endhighlight%}
+
+But the iterator includes features that, although they can be emulated with
+enough templating code, are much faster to achieve with the shortcut functions
+available here.
+
+For example, if you want to get the first 10 pages that have the tag `pastry`,
+you can do this:
+
+{%highlight 'jinja'%}
+{%raw%}
+{% for page in site.pages.has_tags('pastry').limit(10) %}
+* [{{page.title}}]({{page.url}})
+{% endfor %}
+{%endraw%}
+{%endhighlight%}
+
+You can even achieve more elaborate filtering with the [filter syntax][flt],
+too.

+title: Filtering
+---
+
+The PieCrust filtering syntax can be used to select items returned by an
+[iterator object][it] -- including [pagination items][pag] and [assets][ass].
+
+Filters are _named_, and using one on an iterator object just requires to pass
+that name:
+
+{%highlight 'jinja'%}
+{%raw%}
+{% for page in site.pages.filter('my_filter') %}
+...
+{% endfor %}
+{%endraw%}
+{%endhighlight%}
+
+The named filter should be available in the page's configuration header. For
+instance, the following filter matches pages that have the `pastry` tag (_i.e._
+a `tags` metadata value that contains `pastry`) and are not drafts (_i.e._ don't
+have a `draft` metadata value set to `true`):
+
+    ---
+    title: Something
+    my_filter:
+        has_tags: pastry
+        not:
+            is_draft: true
+    ---
+
+See the [templating data reference page][tpldata] for a full list of the
+available filter clauses.
