[Edward Betts]

I'm seeing this error when I try the new KinoSearch:

Any ideas what's going wrong? I'm running on Debian unstable, Perl
version v5.8.8. The code that is giving this error looks like this:

#!/usr/bin/perl

use strict; use warnings;

use KinoSearch::Searcher;

use base qw( KinoSearch::Schema );

__PACKAGE__->init_fields(qw(ingredients intro));

sub analyzer {
    KinoSearch::Analysis::PolyAnalyzer->new( language => 'en' );
}

package main;

my $invindexer = KinoSearch::InvIndexer->new( invindex =>
bigmunch->clobber('index') );

my @items = (

  },

    intro => " As always with curries, lots of ingredients but very

  },
);

$invindexer->add_doc($_) for @items;

$searcher->search( query => 'the' );
