I have a problem with find() method

[freeart]

in posts 30 records: posts.insert({ checkSum: checkSum, (md5) topicId : topic, (integer) topicName : name (long text, length ~ 100-200) }); posts.find(null, null, function(results) { sys.puts(results.length); //if results is "large" callback is not called, if results littleness we see output text 30 });
