AbstractAllGroupHeadsCollector<GH extends AbstractAllGroupHeadsCollector.GroupHead>
This collector specializes in collecting the most relevant document (group head) for each group that match the query.
|
class |
AbstractAllGroupsCollector<GROUP_VALUE_TYPE>
A collector that collects all groups that match the
query.
|
class |
AbstractDistinctValuesCollector<GC extends AbstractDistinctValuesCollector.GroupCount<?>>
A second pass grouping collector that keeps track of distinct values for a specified field for the top N group.
|
class |
AbstractFirstPassGroupingCollector<GROUP_VALUE_TYPE>
FirstPassGroupingCollector is the first of two passes necessary
to collect grouped hits.
|
class |
AbstractGroupFacetCollector
Base class for computing grouped facets.
|
class |
AbstractSecondPassGroupingCollector<GROUP_VALUE_TYPE>
SecondPassGroupingCollector is the second of two passes
necessary to collect grouped docs.
|
class |
BlockGroupingCollector
BlockGroupingCollector performs grouping with a
single pass collector, as long as you are grouping by a
doc block field, ie all documents sharing a given group
value were indexed as a doc block using the atomic
IndexWriter.addDocuments()
or IndexWriter.updateDocuments()
API. |
