hello folks,  
Can you use conditions in the script fields. for example  
If A\<0 then A+B else A-B, where A and B are the fields with datatype number.

thanks in advance...!!!!!!

Mohit,

I do conditional processing in script fields in my code, so yes, very  
possible. Elasticsearch by default uses mvel for scripting which has full  
flow control support. See [http://mvel.codehaus.org/MVEL+2.0+Control+Flow](http://mvel.codehaus.org/MVEL+2.0+Control+Flow)  
for details.
