我有電子書數據的集合MongoDB中像如何在Mongoose中執行查找查詢?
{
"_id" : ObjectId("58b56fe19585b10cd42981d8"),
"cover_path" : "D:\\Ebooks\\uploads\\ebooks\\cover\\1488285665748-img1-700x400.jpg",
"path" : "D:\\Ebooks\\uploads\\ebooks\\pdf\\1488285665257-Webservices Natraz.pdf",
"description" : "ebook",
"title" : "book name",
"tag" : [
"Hindi",
"Other"
],
"__v" : NumberInt(0)
}
現在我想尋找的東西,如果關鍵字是有點比賽從"title:"
則顯示所有相關圖書對象。
我的貓鼬模式是: -
var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var EbookSchema = new Schema({
title: {type:String},
description: {type:String},
path: {type:String,required:true},
cover_path: {type:String,required:true},
tag: [{ type: String }]
});
module.exports = mongoose.model('Ebook', EbookSchema);
我嘗試: -
app.get('/ebook?search=',function(req,res){
var search_key = req.param('search');
Ebook.find(title:'search',function(err, ebooks) {
if (err)
res.send(err);
res.json(ebooks);
});
});
,但我發現我無效怎麼辦?我只想當我搜索一個關鍵字我發現所有相關的對象。
