=head1 NAME

Webpacus::Controller::Search - Search WebPAC data

=head1 SYNOPSIS

See L<WebPAC>, L<Webpacus>

=head1 DESCRIPTION

Catalyst Controller for search fields Hyper Estraier

=head1 METHODS

=over 4

=item default

=cut

sub default : Private {
    my ( $self, $c ) = @_;
    $c->stash->{template} = 'search.tt';
}

=item suggest

Returns results for URLs like C<search/suggest/FieldName>

It will return field from URL (C<FieldName> in example>) and use
same filed in paramerers (comming from form or URL) or if it doesn't
exist field named C<all>.
