Mongoosastic不会在保存时建立索引

const mongoose = require('mongoose');
const mongoosastic = require('mongoosastic');

const Schema = mongoose.Schema;

const BookSchema = new Schema({
  title: String,
  author: String,
  description: String
});

BookSchema.plugin(mongoosastic, {
  createIndex: true, // 设置为true以在保存时自动创建索引
  indexName: 'books', // 索引的名称
  typeName: 'book' // 类型的名称
});

const Book = mongoose.model('Book', BookSchema);

// 创建索引
Book.createMapping((err, mapping) => {
  if (err) {
    console.error('Error creating mapping');
    console.error(err);
  } else {
    console.log('Mapping created');
    console.log(mapping);
  }
});

// 保存数据
const book = new Book({
  title: 'Sample Book',
  author: 'John Doe',
  description: 'This is a sample book'
});

book.save((err) => {
  if (err) {
    console.error('Error saving book');
    console.error(err);
  } else {
    console.log('Book saved');
  }
});
