Parallel search result pipeline evaluations

This Microsoft patent outlines a system and method for evaluating and improving search result pipelines by running multiple indexing and search algorithms in parallel on a local device. Search results are initially displayed based on a default pipeline, but the system monitors how alternative, parallel pipelines rank the same results. When a user selects a result, the system identifies the pipelines that ranked that selected result higher than the default pipeline, labeling them as better aligned with user preferences. This feedback is then aggregated across multiple users and used to identify superior search pipelines for deployment or to personalize the default search experience for individual users.
