node.js - 如何在nodejs中用mongoosastic编写映射

Question

实际上，我现在想从某些字段中删除索引，任何人都可以告诉我如何为我的代码给出下面的代码编写映射；任何人都可以告诉我这有什么问题，或者任何人都可以告诉我什么是正确的做法那。

Blog.createMapping(function(err, mapping){
     if(err){
         console.log('error creating mapping (you can safely ignore this)');
         console.log(err);
     }else{
         mapping: {
              properties: {
                  jeb_no: {
                      index: "no"
                  }
              }
         }  
         console.log('mapping created!');
         console.log(mapping);
    }

});

先感谢您。

示例：此示例用于保存电影信息

var mongoose = require('mongoose')
Schema = mongoose.Schema,
    mongoosastic = require("mongoosastic"),
    var MovieSchema = new Schema({
        movieName: String,
        movieYear: Number,
        imageUrl: String,
        genre: String,
        director: String,
        producer: String,
        cast: String,
        writer: String,
        synopsis: String,
        rating: Number,
        price: Number,
        rentPrice: Number,
        format: String,
        language: String,
        offer: Number,
        quantity: Number,
        offerString: String,
        createDate: Date,
        updateDate: Date,
    });

MovieSchema.plugin(mongoosastic);
Movie = module.exports = mongoose.model('Movie', MovieSchema);
