pymongo query not returning results

I am having trouble with my query, i'm trying to use find contains query on a number of fields, here is my code. I would appreciate any help.

def loadContact(search):
myQuery = {'username' : {'$ne' : session['username']},\
           '$and' : [{'$or' : [\
                 {'username' : '/.*' + search + '.*/i'},\
                 {'surname' : '/.*' + search + '.*/i'},\
                 {'firstName' : '/.*' + search + '.*/i'},\
                 {'email' : '/.*' + search + '.*/i'},\
                 {'company' : '/.*' + search + '.*/i'}]}]}
cursor = db.users.find(myQuery)
payload = []
content = {}
for doc in cursor:
    #this is mocked up code for this question so you can see more clearly
    content = {'username' : cursor[0], 'firstName' : cursor[1]}
    payload.append(content)

return payload

Worth noting the loop does not iterate, the contents of the loop are not of great importance right now if it does not iterate.
