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_aggregationjob.)
Other changes

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 storagewhen 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
tagsparameters.
