This article covers a Bloomreach Experience Manager version 13. There's an updated version available that covers our most recent release.

Export a Lucene Index from a Running Production Instance

This Bloomreach Experience Manager feature requires a standard or premium license. Please contact Bloomreach for more information.
This feature is available since Hippo CMS 12.1.0



Export the Lucene index folder from a running production instance using the Lucene Export Service.


When moving a Bloomreach Experience Manager instance from one environment to another, it may be desirable to move its Lucene index along with it to prevent the need for (time-consuming) reindexing. However, to backup a Lucene index folder normally requires that the application is not running. The optional Lucene Export feature adds a Repository JAX-RS service which enables on-the-fly exporting of the Lucene index from a running production instance.

This page describes how to use the Lucene Export service.

To understand how the Lucene Export service works, see Lucene Export Explained.


  • Before you can use the Lucene Export Service, it must be added to the project and a new project distribution must be created and deployed.
  • The Lucene Export Service is only supported in clustered configurations.

Export a Lucene Index

Download the exported Lucene index folder as a zip file from the following URL:


(where {hostname} is the host name of your environment)

Import a Lucene Index

To import the exported Lucene index into an environment, extract the contents of the zip file (the _1, _2, _3, etc. folders, and file) in the folder:


(where {storageRoot} is the configured repository storage directory location)

After successful startup of the application, the file should disappear automatically.
