Querying for Data (Getting Started)

Basic querying examples


db. collection . find ( { } );

retrieve documents in a collection using a condition ( similar to WHERE in MYSQL )

db. collection.find  ( { key: value } );
    db. users . find ( { email: "" } );


retrieve documents in a collection using Boolean conditions (Query Operators)

NOTE:  find()  will keep on searching the collection even if a document match has been found , therefore it is inefficient when used in a large collection , however by carefully modeling your data and/or using indexes you can increase the efficiency of find()
