_id and _routing now no longer support the 'path' setting on indexes created with 2.0. Indexes created before 2.0 still support this setting for backcompat. closes #6730

=== `_id`
|
|
|
|
Each document indexed is associated with an id and a type. The `_id`
|
|
field can be used to index just the id, and possible also store it. By
|
|
default it is not indexed and not stored (thus, not created).
|
|
|
|
Note, even though the `_id` is not indexed, all the APIs still work
|
|
(since they work with the `_uid` field), as well as fetching by ids
|
|
using `term`, `terms` or `prefix` queries/filters (including the
|
|
specific `ids` query/filter).
|
|
|
|
The `_id` field can be enabled to be indexed, and possibly stored,
|
|
using the appropriate mapping attributes:
