Text search in MongoDB with Regular Expression
For text search in MongoDB with Regular Expression, use $regex. Let us create a collection with documents −
> db.demo519.insertOne({"Value":"50,60,70"});{ "acknowledged" : true, "insertedId" : ObjectId("5e88b9c0b3fbf26334ef6111") } > db.demo519.insertOne({"Value":"80,90,50"});{ "acknowledged" : true, "insertedId" : ObjectId("5e88b9c7b3fbf26334ef6112") } > db.demo519.insertOne({"Value":"10,30,40"});{ "acknowledged" : true, "insertedId" : ObjectId("5e88b9cfb3fbf26334ef6113") }
Display all documents from a collection with the help of find() method −
> db.demo519.find();
This will produce the following output −
{ "_id" : ObjectId("5e88b9c0b3fbf26334ef6111"), "Value" : "50,60,70" } { "_id" : ObjectId("5e88b9c7b3fbf26334ef6112"), "Value" : "80,90,50" } { "_id" : ObjectId("5e88b9cfb3fbf26334ef6113"), "Value" : "10,30,40" }
Following is the query to implement text search in MongoDB with Regex −
> db.demo519.findOne({ Value: { $regex: /50/ } });
This will produce the following output −
{ "_id" : ObjectId("5e88b9c0b3fbf26334ef6111"), "Value" : "50,60,70" }
