field Field Type
================

See :class:`Rollerworks\\Component\\Search\\Extension\\Core\\Type\\FieldType`.

The ``field`` type predefines a couple of options that are then available
on all fields.

The most common one is the :class:`Rollerworks\\Component\\Search\\Extension\\Core\\ValueComparison\\SimpleValueComparison`
to check for duplicated values.
