Using "_" character


(Otis Gospodnetić) #1

Hello,

Is there a general rule for when the "_" character is used in JSON, in
URLs, and other places?

e.g. _script in JSON in http://github.com/elasticsearch/elasticsearch/issues/293
or _source in JSON responses or _all in URL, etc.

Thanks,
Otis

The general rule is for "internal" fields / constructs, elasticsearch uses
_. For example, the _source and _type fields, and for _score which is not
really a field.
