I want to use ES to index logs coming from different processes. Assume I  
have 2 sources: ProcessA and ProcessB Logs from the processes are formatted  
in json. Example log:

{"level":"DEBUG","logger":"REPOSITORY","timestamp":1405982400689,"attrs":{"profile":"ManagementServerA","organization":"FOOBAR"},"thread":"main","message":"Repository.store() : Stored successfully in /central/zone/cef9cccab964"}

How can I get ES to update multiple indexes when it sees a new document ?  
In this case I want indices on the profile and organization values. Do I  
have to

1. Create indexes using the ES REST api before ES sees any logs.
2. Supply an \_index field to each json document
3. Have multiple values in the \_index field to indicate what indexes  
must be updated ? i.e should I have: _"\_index": {"ManagementServerA" ,  
"FOOBAR"}_

Please let me know if this is the correct way to do this.
