    Thanks @ottobackwards 
    
    While I feel like the ES template documentation is good enough for now, I 
really want to investigate something cleaner, probably via 777 but also 
potentially by splitting up indexes as discussed in 
[METRON-1010](https://issues.apache.org/jira/browse/METRON-1010?filter=-2).
