Storing and retrieving json

[Karthick Duraisamy Soundararaj]

Hello all,
                I am facing a need to store and retrieve json string in a
field.

eg.  Imagine a schema like below.
[Please note that this is just an example but not actual specification.]

 <str name="carName" type="string" indexed="true" stored="false">
 <str name="carDescription" type="string" indexed="false" stored="false">

carDescription is a json string . An example would be
   { "model":1988 "type":"manual"}

I dont need to search on the carDescription. I want to store some json data
and retreive. When i feed json data to carDescription field through DIH,
 the response for the query is like below

   {\ "model\":1988 \"type\":\"manual\"}

All the quotes are escaped. I dont want this. I want the original
unmodified data. Is there a way to do this?

Thanks,
Karthick
