要通过单词查找 MongoDB 文档，请使用 find() 并将单词设置为 −
word/i
Let us create a collection with documents −
> db.demo212.insertOne({"details":[{"Name":"John Doe"}]});
{
"acknowledged" : true,
"insertedId" : ObjectId("5e3e2c7603d395bdc21346ff")
}
> db.demo212.insertOne({"details":[{"Name":"Chris Brown"}]});
{
"acknowledged" : true,
"insertedId" : ObjectId("5e3e2c8003d395bdc2134700")
}
> db.demo212.insertOne({"details":[{"Name":"Robert doe"}]});
{
"acknowledged" : true,
"insertedId" : ObjectId("5e3e2c8a03d395bdc2134701")
}
借助 find() 方法显示集合中的所有文档 −
> db.demo212.find();
这将产生以下输出 −
{ "_id" : ObjectId("5e3e2c7603d395bdc21346ff"), "details" : [ { "Name" : "John Doe" } ] }
{ "_id" : ObjectId("5e3e2c8003d395bdc2134700"), "details" : [ { "Name" : "Chris Brown" } ] }
{ "_id" : ObjectId("5e3e2c8a03d395bdc2134701"), "details" : [ { "Name" : "Robert doe" } ] }
以下是通过单词查找 MongoDB 文档的查询 −
> db.demo212.find({"details.Name":/doe/i});
这将产生以下输出 −
{ "_id" : ObjectId("5e3e2c7603d395bdc21346ff"), "details" : [ { "Name" : "John Doe" } ] }
{ "_id" : ObjectId("5e3e2c8a03d395bdc2134701"), "details" : [ { "Name" : "Robert doe" } ] }
