hi all. in the elasticsearch v1.7 docs, I see "Deprecated in 1.5.0" on the _routing page just below the info for the "path" field.
my question is: does that mean that "path" is deprecated or is "_routing" deprecated.
if path is deprecated but _routing isn't, how do we specify what to route on?
if routing is deprecated, has it been replaced by some other mechanism as this is an important performance feature when you have a large index?
