Elasticsearch 0.19.0.RC3

Release Notes

Upgrade Notes:

  • Upgrading from 0.18 requires issuing a full flush of all the indices in the cluster (curl host:9200/_flush) before shutting down the cluster, with no indexing operations happening after the flush.
  • The local gateway state structure has changed, a backup of the state files is created when upgrading, they can then be used to downgrade back to 0.18. Don’t downgrade without using them.

New features:

  • API: Multi Search (#1722)
  • Date Mapping: Support “date math” when searching (#1708)


  • Indices query should accept alias names (#1698)
  • Return 503 for search against a node which is not yet ready (#1713)
  • Failed shards allocation can “poison” allocation and might cause not allocating other shards (#1717)
  • Analysis: Add trim token filter that trims whitespaces (#1693)
  • Index Templates: Allow to place them under config/templates (#1703)
  • Local Gateway: Delete dangling indices after a (configurable) timeout, and not immediately (#1718)
  • Search: Allow to execute search with no parameters (#1696)

Bug fixes:

  • Retrieving byte type stored field fails (#1702)
  • StackOverflowError when accessing NodeIndicesStats.refresh() (#1706)
  • top_children query returns no results when child field has the same name as a nested field as a nested field in the parent mapping (#1709)
  • Search: When using _all for types, field name/type resolution might fail (#1704)
