MongoDB Regular Expression Search - Starts with using javascript driver and NodeJS

Question

I\'m using the JavaScript mongodb driver from nodejs. I want to do this query in my JavaScript function:

db.mycollection.find({Zip:/^94404/}); 

Answer 1

$options => i for case insensitive search

Start with string

db.collection.find({zip:{'$regex' : '^string', '$options' : 'i'}})

End with string

db.collection.find({zip:{'$regex' : 'string$', '$options' : 'i'}})

Contains string

db.collection.find({zip:{'$regex' : 'string', '$options' : 'i'}})

Doesn't Contains string

db.collection.find({zip:{'$regex' : '^((?!string).)*$', '$options' : 'i'}})
