Hi there,

I'm new to ES and making some progress. First newbie benchmarks are very  
promising. I can "mget" and filter docs by ids with 500000 ids at one  
request and get them back in 17 / 20 secs on a VM on a Laptop. That's the  
good news.

But I still can't get some probably simple things done (like setting some  
settings) and other things take me a lot of trial and error and reading  
back and forth the guide. The issue is "operation" in opposite to  
"understanding", which will certainly take its time.

So, is there a reference documentation?

E.g. for the settings, which gives a complete overview of all the settings  
available, further of the available methods to set those settings (API or  
elasticsearch.yml) and the allowed fields? E.g., I find it hard to  
understand from the guide when to use indices.xyz vs. index.xyz or wether I  
need to use "index.store :memory" or "index.store.memory: true" and where  
to set it.

Similiar matter regarding the DSL ...

Maybe it's because the big picture is not there yet, but currently I feel a  
bit stupid :-).

Cheers,

Jan
