Package WebGUI::Asset::Wobject::Search
=head1 DESCRIPTION
Asset used to search WebGUI content.
=head1 METHODS
These methods are available from this package:
=cut
#-------------------------------------------------------------------
=head2 definition ( class, definition )
This method defines all properties of a Search and is used to autogenerate most methods.
=head3 class
$class is used to make sure that inheritance works on Assets and Wobjects.
=head3 definition
Definition hashref from subclasses.
=head3 Search specific properties
These properties are added just for this asset.
=head4 templateId
ID of a tempate from the Search namespace to display the search results.
=head4 searchRoot
An asset id of the point at which a search should start.
=head4 classLimiter
An array reference of asset classnames that are valid for the search.
