=head1 NAME

KSx::Search::MockScorer - Matcher with arbitrary docs and scores.

=head1 DESCRIPTION 

Used for testing combining L<Matchers|KinoSearch::Search::Matcher> such as
ANDScorer, MockScorer allows arbitrary match criteria to be supplied,
obviating the need for clever index construction to cover corner cases.

MockScorer is a testing and demonstration class; it is unsupported.

=head1 CONSTRUCTORS

=head2 new( [I<labeled params>] )

=over

=item *

B<doc_ids> - A sorted array of L<doc_ids|KinoSearch::Docs::DocIDs>.

=item *

B<scores> - An array of scores, one for each doc_id.
