Each item in the list of input titles is passed to the subfilter in turn. The subfilter transforms the input titles into the form needed for sorting. For example, the subfilter `[length[]]` transforms each input title in the number representing its length, and thus sorts the input titles according to their length.

Note that subfilters should return the same number of items that they are passed. Any missing entries will be treated as zero or the empty string. In particular, when retrieving the value of a field with the [[get Operator]] it is helpful to guard against a missing field value using the [[else Operator]].
