Fusion AI 4.2.2 Release Notes

Release date: 17 May 2019

New features

No new features were introduced in this release.


  • Recommender jobs are no longer scheduled by default; they must now be scheduled manually or run on demand. (Previously, default recommender jobs were automatically scheduled to run after the _user_item_preferences_aggregation job.)

Other changes

  • The Spark driver now writes error.log and output.log files to var/log/api instead of var/api/work.

  • Query Rewriting UI bug fixes:

    • Fixed an issue in Fusion Server 4.2.0 and 4.2.1 that caused the UI’s search feature to return a Problem with underlying storage when a query was : followed by an additional query term.

    • Fixed a bug that caused the Query Rewriting UI to display an error window that could not be closed.

  • Signals from the Simulator are no longer sent to the signals collection.

  • Fixed an issue in the Text Tagger query stage which prevented query rewrites from working after Save Tags in Context had been enabled.

  • Business rules defined with tags are no longer triggered by queries that contain no tags parameters.
