> for query like
> {code}
> select * from city where city like 'ACM%'
> {code}
> Current query expression generated which is correct for javascript environment is 
> {code}
> $match:{ "city" : "/^ACM/"}
> $project:{ "_m0" : "$_id" , "_m1" : "$city" , "_m2" : "$state" , "_m3" : "$pop"}
> {code}
> but when executing from java, java driver wants like
> {code}
> $match:{ "city" : { "$regex" : "^ACM"}}
> $project:{ "_m0" : "$_id" , "_m1" : "$city" , "_m2" : "$state" , "_m3" : "$pop"}
