为什么这种猫鼬文字搜索无法正常工作

Question

Even though I have similar data in collection, result always comes back empty. I have ingredients in array[object]. That means qty:1 unit:spoon ing:salt and I want only ing to be searchable. I have mongoose debug enabled and it shows:

Mongoose: recipes.ensureIndex({ 'Ingridients.ing': 'text' }) { background: true, safe: undefined }

This is the code:

var RecipesSchema = new mongoose.Schema({
  Name: {type: String, required: true},
  Desc: String,
  Ingridients: [{qty:Number, unit:String, ing:{ type: String, index: "text" } }],
  created: { type: Date }
});

Recipe.find({ $text : { $search : "salt egg potato peper" } }, 
            { score : { $meta: "textScore" }
    })
    .sort({ score : { $meta : 'textScore' } })
    .exec(function(err, recipe) {
        // callback
        if(err) console.log(err);
            res.render('list', { recipes: recipe });
});

after i tried on localhost and it worked, switched on mongolab.com by dropping and recreating collection and indexes again. it was not able to index correctly

ERR: planner returned error: need exactly one text index for $text query',  code: 17007
