Improvements

Synonym pairs are now grouped and treated as one term when for better compatibility with Solr’s "minimum match" (
mm
) query parameter. -
Query rewriting accuracy is improved in this release.
-
Parallel Bulk Loader (PBL) jobs and Script jobs can now be configured to set environment variables. In the Fusion UI, click Advanced to see this option.
-
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.)
