Question

My aim is to create a map function like this

map = function () { var key = {key:this.name-1}; emit(key, {count:1}); }

I pass the parameter “name-1” in a java code. But mongo takes it as “name minus 1”. So key becomes and integer and so during map reduce I get NaN problem.

The map actually looks like this

map = function () { var key = {key:this.name - 1}; emit(key, {count:1}); }

how to overcome this problem?

Phew finally this works.

map = function () { var key = {key:this["name-1"]}; emit(key, {count:1}); }
