    New features

    • App Insights

      App Insights provides detailed, real-time, searchable reports and visualizations derived from your signals data. It also provides alerts and triggers to notify you when specific events occur.

      Pre-4.0 signals data will not produce useful visualization in App Insights. New signals generated with Fusion 4.0 will produce the best results.

    • New jobs

      • Head/Tail Analysis

        Perform head/tail analysis of queries from collections of raw or aggregated signals, to identify underperforming queries and the reasons. This information is valuable for configuring better synonyms, auto-suggest, recommendations, and so on, in order to improve conversion rates.

      • Token and Phrase Spell Correction

        Extract tail tokens (one word) and phrases (two words) and find similarly-spelled head tokens and phrases. If several matching heads are found for each tail, the job can compare and pick the best correction using multiple configurable criteria.

    Improvements

    • Experiment management features

      The Fusion UI now includes interfaces for running and managing experiments.

    Other changes

    • Bisecting Kmeans Clustering Jobs are now called Document Clustering Jobs

    • The data structure for signals has changed

      See Signals for complete details about the new structure.

    • The Experiments API is no longer experimental

      The API and other experiments features are now fully functional.

    • Aggregator API is deprecated

      The /aggregator endpoints are deprecated in this release. Aggregations are now managed through the /spark endpoints.
