You can find like this example
db.users.insert(name: 'paulo')
db.users.insert(name: 'patric')
db.users.insert(name: 'pedro')
db.users.find(name: /a/) //like '%a%' out: paulo, patric
db.users.find(name: /^pa/) //like 'pa%' out: paulo, patric
db.users.find(name: /ro$/) //like '%ro'
db.students.aggregate(
$project: studentNo:"$studentNo" , name: $concat: [ "$firstName", " ", "$lastName" ] ,age:"$age",
$match: "name":/Suraj/)
project is used to list down all the coloumns plus concat two coloumns and then search on new records
aggregation is a way in MongoDB to where we can add clauses like where, having in sql
for more understanding, you can learn from

You can find like this example
db.users.insert(name: 'paulo')
db.users.insert(name: 'patric')
db.users.insert(name: 'pedro')
db.users.find(name: /a/) //like '%a%' out: paulo, patric
db.users.find(name: /^pa/) //like 'pa%' out: paulo, patric
db.users.find(name: /ro$/) //like '%ro'
db.students.aggregate(
$project: studentNo:"$studentNo" , name: $concat: [ "$firstName", " ", "$lastName" ] ,age:"$age",
$match: "name":/Suraj/)
project is used to list down all the coloumns plus concat two coloumns and then search on new records
aggregation is a way in MongoDB to where we can add clauses like where, having in sql
