mongodb处理中文索引与查找字符串详解_MongoDB_

 var ArticleSchema = new Schema({ created: { type: Date, default: Date.now }, title: { type: String, default: '', trim: true, required: 'Title cannot be blank' }, abstract: { type: String, default: '', trim: true }, abstractImg: { type: String, default: 'http://www.doocr.com/modules/core/client/img/brand/font-ocr.png', trim: true }, content: { type: String, default: '', trim: true }, category: { type: String, default: 'news', trim: true }, user: { type: Schema.ObjectId, ref: 'User' }, toPublish: { type: Boolean, default: true }, comments: [CommentSchema] });

 > db.articles.find( { $text: { $search: "coffee" } } ) Error: error: { "waitedMS" : NumberLong(0), "ok" : 0, "errmsg" : "text index required for $text query", "code" : 27 }

 db.articles.createIndex( {title: "text", content: "text" })

 > db.articles.createIndex( ... { ... title: "text", ... content: "text" ... } ... )

 { "createdCollectionAutomatically" : false, "numIndexesBefore" : 1, "numIndexesAfter" : 2, "ok" : 1 }

 > db.articles.find( { $text: { $search: "coffee" } } )

 > db.articles.find( { $text: { $search: "操作" } } ) { "_id" : ObjectId("58b0eb5a136dc51b541eaf81"), "user" : ObjectId("589c8d22f7d9dc15989be255"), "comments" : [ ], "toPublish" : true, "category" : "blog", "content" : "

其实就是使用ubuntu 16的安装方式，参考网址：
https://docs.mongodb.com/master/tutorial/install-mongodb-on-ubuntu/

我的操作步骤：
1.倒入key：sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv EA312927

2. 创建mongodb的软件源：
/etc/apt/sources.list.d/mongodb-org-3.2.list
操作：
echo "deb http://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.2.list

3. 更新系统：
sudo apt update
之后查看所有可以更新的软件：
sudo apt list --upgradable
然后升级所有软件：
sudo apt upgrade

4. 安装mongodb ：
sudo apt install -y mongodb-org
也可以指定版本安装：
sudo apt-get install -y mongodb-org=3.2.8 mongodb-org-server=3.2.8 mongodb-org-shell=3.2.8 mongodb-org-mongos=3.2.8 mongodb-org-tools=3.2.8
不过我不使用这种方式。

5. 添加systemd 自启动条目：
sudo vim /lib/systemd/system/mongod.service
添加内容：
[Unit]
Description=High-performance, schema-free document-oriented database
After=network.target
Documentation=https://docs.mongodb.org/manual

[Service]
User=mongodb
Group=mongodb
ExecStart=/usr/bin/mongod --quiet --config /etc/mongod.conf

[Install]
WantedBy=multi-user.target

6. 使能和启动服务：
sudo systemctl enable mongod.service
sudo systemctl start mongod.service

查看状态，一切ok。
sudo systemctl status mongod.service

7. 查看服务启动端口是否ok：
azuo1228@mint ~/webproj/mjs2/meanjs $ netstat -apn | grep mong
