    Parameterized Boosting Stage

    Table of Contents

    The Parameterized Boosting query pipeline stage reads the boostValues (in List<DocumentResult> format) from the context variable (added by a Rollup Aggregation stage or a JavaScript stage), and adds boosts to the main query using bq or boost based on the stage configuration. The weights for the boost values can also be scaled.
