New Features

New Lucidworks AI pipeline stages are introduced in this release to enrich your index and search with Generative AI predictions:
  • The LWAI Prediction index stage allows for asynchronous and synchronous enrichment that add predictions when indexing your data.
    See Configure the LWAI Prediction index Stage for more detailed instructions about configuring this stage.
  • The LWAI Prediction query stage fetches synchronous predictions to add to your query response.
See Generative AI for more details about Lucidworks AI’s Generative AI capabilities, including pre-trained models hosted by Lucidworks. You can also use LWAI custom trained embedding and LWAI hosted pre-trained models with these new stages. A new API endpoint, /index-pipelines/{id}/async-enrichment/skip-pending, can be used to clear the queue of outstanding asynchronous prediction index requests if needed.

​
Removals

​
Bitnami removal

Fusion 5.9.7 will be re-released with the same functionality but updated image references. In the meantime, Lucidworks will self-host the required images while we work to replace Bitnami images with internally built open-source alternatives. If you are a self-hosted Fusion customer, you must upgrade before August 28 to ensure continued access to container images and prevent deployment issues. You can reinstall your current version of Fusion or upgrade to Fusion 5.9.14, which includes the updated Helm chart and prepares your environment for long-term compatibility. See Prevent image pull failures due to Bitnami deprecation in Fusion 5.9.5 to 5.9.13 for more information on how to prevent image pull failures.

Bug fixes

  • Fixed an issue where some collections were not displayed in the Collections Manager if the system contained one or more orphaned child collections.
    Note that orphaned child collections are not displayed in the Collections Manager by design, but they are discoverable using the API or the Object Manager.
