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.

  • Allow to customize quote analyzer to be used when quoting text in a query_string (#1931)

  • Percolator Index: Don’t index the query element in a percolated query (#1949)
  • Query DSL: filtered query to support null filter or {} filter (in which case, just the query is executed) (#1900)
