Hi, 

      Actually, search need go over all fields,  every field has special 
definition, the number of fields is too big to remember, 
I need  search all fields for any keywords, return matched docs and field 
name to request.

     Why so many fields, cause the data come from tables of database. 
Client want a system to search any data conveniently.

     There are other problems like, search results from two tables need do 
a join-like operation.

     These requirements exceed  ES capcacity, I am not sure.

Thanks.
