/**
 * Description of the total number of hits of a query. The total hit count can't generally be
 * computed accurately without visiting all matches, which is costly for queries that match lots of
 * documents. Given that it is often enough to have a lower bounds of the number of hits, such as
 * "there are more than 1000 hits", Lucene has options to stop counting as soon as a threshold has
 * been reached in order to improve query times.
 *
 * @param value The value of the total hit count. Must be interpreted in the context of {@link
 *     #relation}.
 * @param relation Whether {@link #value} is the exact hit count, in which case {@link #relation} is
 *     equal to {@link Relation#EQUAL_TO}, or a lower bound of the total hit count, in which case
 *     {@link #relation} is equal to {@link Relation#GREATER_THAN_OR_EQUAL_TO}.
