It is up to the user to ensure that IDs are unique across the index.
[[routing-index-partition]]
==== Routing to an index partition
An index can be configured such that custom routing values will go to a subset of the shards rather
than a single shard. This helps mitigate the risk of ending up with an imbalanced cluster while still
reducing the impact of searches.
This is done by providing the index level setting <<routing-partition-size,`index.routing_partition_size`>> at index creation.
As the partition size increases, the more evenly distributed the data will become at the
expense of having to search more shards per request.
When this setting is present, the formula for calculating the shard becomes:
shard_num = (hash(_routing) + hash(_id) % routing_partition_size) % num_primary_shards
That is, the `_routing` field is used to calculate a set of shards within the index and then the
`_id` is used to pick a shard within that set.
To enable this feature, the `index.routing_partition_size` should have a value greater than 1 and
less than `index.number_of_shards`.
Once enabled, the partitioned index will have the following limitations:
* Mappings with parent-child relationships cannot be created within it.
* All mappings within the index must have the `_routing` field marked as required.

The `index` option controls whether field values are indexed. It accepts `true`
or `false`. Fields that are not indexed are not queryable.
NOTE: For the legacy mapping type <<string,`string`>> the `index` option only accepts legacy values `analyzed` (default, treat as full-text field), `not_analyzed` (treat as keyword field) and `no`.

Indexes imported from 2.x *only* support `string` and not `text` or `keyword`.
To ease the migration from 2.x Elasticsearch will downgrade `text` and `keyword`

mappings applied to indexes imported from 2.x into `string`. While long lived
indexes will eventually need to be recreated against 5.x before eventually
upgrading to 6.x, this downgrading smooths the process before you find time for
