SUMMARY: NESTED | FIELD | CONSTR | METHOD | DETAIL: FIELD | CONSTR | METHOD |
An interface representing a group (cluster) of related hits.
If isJunkCluster()
method returns true
then this cluster contains documents that are grouped together,
but no clear semantic relation has been detected. Such clusters may
be hidden in the user interface layer, unless someone wishes to
see an explicit group of documents that didn't belong anywhere else.
