Tutorial requests - please submit

Hi all

As we all know, the documentation for ElasticSearch could be improved.
The site needs more tutorials, especially for beginners.

However, there are so many subjects that could be covered, that I tend
to get overwhelmed with topics, and end up writing none.

Proposal:

    If you have a good topic for a tutorial, please add it to the
    documentation issues list:
    https://github.com/elasticsearch/elasticsearch.github.com/issues
    
    with the title "Tutorial: YOUR TOPIC"

Unfortunately, github has disabled voting on issues, but if you add a
comment to any issues that you prefer, then that will give us an idea of
which the most wanted tutorials are.

Also, if anybody feels inclined to write a tutorial, then please feel
free to pick one from the list, or to add an unlisted tutorial.

thanks

Clint
