TotalHits
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.
Parameters
The value of the total hit count. Must be interpreted in the context of .relation.
Whether .value is the exact hit count, in which case .relation is equal to Relation.EQUAL_TO, or a lower bound of the total hit count, in which case .relation is equal to Relation.GREATER_THAN_OR_EQUAL_TO.
Types
How the TotalHits.value should be interpreted.
