Searching a specific domain name from URL records in MongoDB?

MongoDBDatabaseBig Data Analytics

To search for a specific domain name, use /i. Let us create a collection with documents −

> db.demo219.insertOne({"details":{"WebsiteURL":"www.EXAMPLE.com"}});
{
   "acknowledged" : true,
   "insertedId" : ObjectId("5e3e667203d395bdc2134718")
}
> db.demo219.insertOne({"details":{"WebsiteURL":"www.gmail.com"}});
{
   "acknowledged" : true,
   "insertedId" : ObjectId("5e3e667803d395bdc2134719")
}
> db.demo219.insertOne({"details":{"WebsiteURL":"www.example.com"}});
{
   "acknowledged" : true,
   "insertedId" : ObjectId("5e3e667f03d395bdc213471a")
}

Display all documents from a collection with the help of find() method −

> db.demo219.find();

This will produce the following output −

{ "_id" : ObjectId("5e3e667203d395bdc2134718"), "details" : { "WebsiteURL" : "www.EXAMPLE.com" } }
{ "_id" : ObjectId("5e3e667803d395bdc2134719"), "details" : { "WebsiteURL" : "www.gmail.com" } }
{ "_id" : ObjectId("5e3e667f03d395bdc213471a"), "details" : { "WebsiteURL" : "www.example.com" } }

Following is the query to search a specific domain name −

> db.demo219.find({"details.WebsiteURL": /example/i});

This will produce the following output −

{ "_id" : ObjectId("5e3e667203d395bdc2134718"), "details" : { "WebsiteURL" : "www.EXAMPLE.com" } }
{ "_id" : ObjectId("5e3e667f03d395bdc213471a"), "details" : { "WebsiteURL" : "www.example.com" } }
