将 $text 与 mongoose 一起用于文本搜索不起作用

Question

我正在尝试使用 $text 进行文本搜索，如下所示

var express = require('express');
var app = express();
var mongoose = require('mongoose');
var bodyparser = require('body-parser');
var port = process.env.PORT || 8000;
var router = express.Router();
var cors = require('cors');
var Schema = mongoose.Schema;
var router = express.Router();
var exec = require('exec');
app.use(bodyparser.json());

//establish the connection
var db=mongoose.connect('mongodb://localhost/book_publisherSearch');


//define the schema
var authorSchema = new mongoose.Schema(
    {
        authorId : Number,
        Description : String,
        firstName : String
    });

authorSchema.index({ firstName: 'text'});


var Authors= mongoose.model('Authors',authorSchema);

router.route('/search')
    .get(function(req,res){
        Authors.find({ $text : { $search : "Bharath" }},function(err,authors){
            console.log("inside search");
            res.send(authorss);
        })
    })


app.use(router);
app.listen(port);

但是当运行我得到的错误是

c:\Users\zendynamix\IdeaProjects\node_modules\mongoose\node_modules\mongodb\lib\mongodb\connection\base.js:246
        throw message;

    Process finished with exit code 1

在数据库中我有一个 Authors 集合，其中很少有包含名字的集合有 Bharath

请指出我做错了什么谢谢

Answer 1

在我添加了一些文档后，集合中没有文档，它工作正常

将 $text 与 mongoose 一起用于文本搜索不起作用

use of $text with mongoose for text search is not working
