Hi Jerome ,
thanks for your response.
I never knew about multivalued fields.
Will give a try about it and see if that suits my need.


But i dont understand this 
* You could have a mixed index with user and project entries in the
same index, so if you search for a name, you'd find users and projects
matching that name.

Could you please tell me in detail as how i can do that.
