Examples of ElasticsearchMergePolicy

org.elasticsearch.index.merge.policy.ElasticsearchMergePolicy
A {@link MergePolicy} that upgrades segments and can upgrade merges.
It can be useful to use the background merging process to upgrade segments, for example when we perform internal changes that imply different index options or when a user modifies his mapping in non-breaking ways: we could imagine using this merge policy to be able to add doc values to fields after the fact or on the opposite to remove them.
For now, this {@link MergePolicy} takes care of moving versions that used tobe stored as payloads to numeric doc values.
