How should I configure the logstash output so that the data gets into a sub index.  
E.g:  
`index => "/food/%{food_type}"`

where food\_type is a field I have created in filter {}

There is no such thing as a "sub index". Index names can't contain slashes.

The proper nomenclature I was looking for is **type**

The elasticsearch output uses the `type` field as the document type. You can override that with the elasticsearch output's `document_type` option.
