SKP's Java/Java EE Gotchas: Clustered Nodes Issue Using Apache Lucene 5.4.y Different Indexes / Results Using Same Data on Different Machines [Clustered Nodes] [Hibernate Search 5.5.x / Apache Lucene 5.4.y] by Join the DZone community and get the full member experience.Join For Free So, We just spent about 28+ days — using Stack Overflow and Hibernate Search Forums as also various other resources to 'FIX' the strangest of issues using Hibernate Search and Apache Lucene. The right help or pointer came from the 'Hibernate Search Committers/Creators' (Official Forums). Thanks a lot to ' sanne.grinovero'. Issue Description: In a (non-replicated) clustered environment, if the Indexing by Lucene or Hibernate Search is done from the Same Database (Instance) using the Same Data the Results obtained are Different on Different Nodes. In other words, the Same Data from the Same Database Instance Indexed using the Same Code Yields a Different Result Set for the Same Search Term (Index Contents are Different on Different Machines).
