Are mongodb ids unique ?

How do I query mongodb with “like”?


SQL Server like used “%” operator but in mongodb used “.*” operator.

In the below example, I am looking for something that contains “ak” as string.

Query 1:   db.customers.find({"name": /.*ak.*/})
Query 2:  db.customers.find({"name": /ak/})


We can also use regex, the example look like below.

db.customers.find({ "name": { $regex: /ak/i } })
OR
db.customers.find({"name": /^ak/})
OR
db.customers.find({'name': {'$regex': 'ak'}})
