    Improvements

    • Phrase Extraction job improvements

      • The job now trims low-confidence phrases based on likelihood.

      • The job adds a review tag on the result to facilitate the review process based on beginning and ending POS and likelihood.

      • The output now connects phrase tokens with an underscore (_) to make a single token per phrase so that complete phrases can be used as facets.

      • New metadata fields:

        • phrases_count shows how many times the phrases appear in the documents.

        • word_num shows how many words are in the phrase.

      • This release includes optimizations to the default Lucene analyzer configuration.

      • Output names are updated for clarity, such as llr to likelihood and ngram to phrases.

    • The Ranking Metrics job now correctly accepts values for the queryPipelines property in the Fusion UI.

    • The Solr Query pipeline stage has two new properties to configure signals:

      • responseSignalsEnabled

        Disable this option to prevent the stage from generating a response signal containing metadata about the response from Solr.

        Response signals are used by App Insights and experiments.

        In auto-complete pipelines, disable this option to avoid generating a response signal for each keystroke.

      • excludeResponseSignalMatchRules

        If responseSignalsEnabled is "true", then you can prevent generating a response signal based on specific parameters in the query, such as to enable response signals in general but to disable them for auto-complete queries.

    Other changes

    • The Spark driver now cleans up $FUSION_HOME/var/spark/Spark-workDir-* directories and shaded jars correctly on Windows to prevent excessive disk consumption.

    • For installations that were upgraded from 3.1.x to 4.1.0, upgrading to 4.1.1 resolves an issue that prevented successful signal aggregations with the Parameterized SQL Aggregation job.
