Noble Paul commented on SOLR-1682:
----------------------------------


bq. But now also a search is done twice. Shouldn't it be better to have two complete distinct collectors that don't depend on one another?

Both the collectors are designed to complement each other so that one can piggyback on other and minimize the code/work

bq. The field group.numFound is then added as well. Why did you gave it a different name?

The names are up for debate . Let us reach a consensus on that . When collapse.threshhold=1 collapse.cout/collapse.groupSize can be avoided
