Hi :)
Yes we can add a section about that if it helps, but a filter type is basically a form type.
In the current version of the bundle the only difference between types we provide and types provided by SF is a filter type extends AbstractFilterType instead of directly extends Symfony\Component\Form\AbstractType. Filters are applied by the Filters classes, these classes are defined as services in filters.xml

Example:
If you look a the DateFilterType you will see the class is simple, we just define the transformer_id to extract data from the form. Then the date filter is applied on the query builder by the DateFilter.
Note that DateFilter::getName() return the same name as DateFilterType::getName(), this is the way a filter class is related to a filter type.

Figure out how FilterType, data transformer and Filter classes works and how they are connected (via events as far as I understand) takes some time. So some docs would be very helpfull.
