             Summary: Like operator does not work in MongoDB translator
                 Key: TEIID-2727
                 URL: https://issues.jboss.org/browse/TEIID-2727
             Project: Teiid
          Issue Type: Bug
          Components: Misc. Connectors
    Affects Versions: 8.4
            Reporter: Ramesh Reddy
            Assignee: Ramesh Reddy
             Fix For: 8.6


The issue is similar to http://stackoverflow.com/questions/5608584/how-to-query-mongodb-with-like-using-the-java-api

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"}
{code}
