Hi, While reading Lucene source code, I have a tiny question about the selection of threshold：threshold = value >>> 3.
eg. in NumericComparator#updateCompetitiveIterator(), as 'threshold = iteratorCost >>> 3' a condition for whether to update iterator eg. in IndexOrDocValuesQuery, as 'threshold = cost() >>> 3' a condition for choosing indexScorerSupplier or dvScorerSupplier So the selection of threshold base some theory or tradeoff or other reason? Could I get some suggestion？ --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
