一.Group

1.group.query
2.group.field
3.group.func
4.group.sort
5.group.limit:the limit for the number of documents in each group
6.group.offset:the offset for the doclist of each group
7.group.main:treat the first group result as the main result.  true/false
8.group.format:treat the first group result as the main result.  true/false
9.group.cache.percent:Whether to cache the first pass search (doc ids and score) for the second pass search.Also defines the maximum size of the group cache relative to maxdoc in a percentage.Values can be a positive integer, from 0 till 100. A value of 0 will disable the group cache.The default is 0.
10.group.truncate:Note: Since you can supply multiple fields to group on, but only have a facets for the whole result. It only makes sense to me to support these parameters for the first group.Whether the docSet (for example for faceting) should be based on plain documents (a.k.a UNGROUPED) or on the groups (a.k.a GROUPED).The docSet will only the most relevant documents per group. It is if you query for everything with group.limit=1
11.group.ngroups:Whether the group count should be included in the response
12.group.facet:Whether to compute grouped facets based on the first specified group
13.group.distributed.first:Retrieve the top search groups (top group values) from the shards being queried
14.group.distributed.second:Retrieve the top groups from the shards being queries based on the specified search groups in the GROUP_DISTRIBUTED_TOPGROUPS_PREFIX parameters
15.group.topgroups.
