Examples of TermAllGroupsCollector

org.apache.lucene.search.grouping.TermAllGroupsCollector
A collector that collects all groups that match the query. Only the group value is collected, and the order is undefined. This collector does not determine the most relevant document of a group.
Implementation detail: an int hash set (SentinelIntSet) is used to detect if a group is already added to the total count. For each segment the int set is cleared and filled with previous counted groups that occur in the new segment. @lucene.experimental
