    speed up TestSimpleExplanationsWithFillerDocs (#516)
    
    This is the slowest test suite, runs for ~ 60s, because between every
    document it adds 2048 "filler docs". This just adds up to a ton of
    indexing across all the test methods.
    
    Use 2048 for Nightly, and instead a smaller number (4) for local builds.
