Hi Sinan,
Thank you for the links and your suggestions. However, I did not quite
understand your suggestions and I tried this map function which did not
work:
function(doc) {
var judge = function (no1, no2) {
var unexpect = "X";
var letter1 = unexpect, letter2 = unexpect;
for (var i in this.chr) {
var chr = this.chr[i];
if (chr.no == no1) {
letter1 = chr.letter;
} else if (chr.no == no2) {
letter2 = chr.letter;
}
}
if (letter1 != letter2 && letter1 != unexpect && letter2 !=
unexpect) {
return true;
}
return false;
};
emit(judge(n1, n2), doc);
}
Could you please explain your ideas a little more?
Thank you in advance.
Mic
