[KinoSearch] DocReader documentation

[Nick Wellnhofer]

The following PODs

http://search.cpan.org/~karman/KinoSearch-0.30_083/lib/KinoSearch/Index/DocReader.pod
http://search.cpan.org/~karman/KinoSearch-0.30_083/lib/KinoSearch/Index/SegReader.pod

say that one can fetch documents from a DocReder with

my $doc = $doc_reader->fetch($doc_id);

That didn't work for me. I had to use

my $doc = $doc_reader->fetch(doc_id => $doc_id);
