--------------------------------------------------

  
  Notes:
   * Any number of group commands (group.field, group.func, group.query) may be specified
in a single request.
+ 
+ 
+ = Known Limitations =
   * Distributed search support for result grouping has not yet been implemented.
+  * Support for missing values (groupValue=null) has not yet been implemented.
+  * Support for grouping on a multi-valued field has not yet been implemented.
+  * Support for faceting after collapsing has not been implemented (faceting works like normal,
with grouping having no effect)
+  * Further performance improvements are planned soon!
