Methods

Name Description
Merge<T>(ITopGroups<T>[], Sort, Sort, Int32, Int32, TopGroups.ScoreMergeMode)

Merges an array of TopGroups, for example obtained from the second-pass collector across multiple shards. Each TopGroups must have been sorted by the same groupSort and docSort, and the top groups passed to all second-pass collectors must be the same.

NOTE: We can't always compute an exact totalGroupCount. Documents belonging to a group may occur on more than one shard and thus the merged totalGroupCount can be higher than the actual totalGroupCount. In this case the totalGroupCount represents a upper bound. If the documents of one group do only reside in one shard then the totalGroupCount is exact.

NOTE: the topDocs in each GroupDocs is actually an instance of TopDocsAndShards
