Harvest::Controller::SOIFFilter::Description - add a description of an object

DESCRIPTION

The Harvest schema uses a ``Description'' attribute to contain a short description of the object. A number of summarisers create this from data contained within the object, however many do not.

This filter generates a ``Description'' attribute, if one does not exist, from the first few characters of the Full-Text (or if that does not exist, the Partial-Text) attribute.

PARAMETERS

A number, being the number of characters to extract to form the description. This defaults to being 240 characters, which is approximately 3 lines of text.
