Subject [Solr Wiki] Update of "FieldCollapsing" by martijnvg
Date Sun, 07 Aug 2011 10:39:21 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Solr Wiki" for change notification.

The "FieldCollapsing" page has been changed by martijnvg:

  ||group.format||grouped/simple||if simple, the grouped documents are presented in a single
flat list.  The start and rows parameters refer to numbers of documents instead of numbers
of groups.||
  ||group.main||true/false||If true, the result of the first field grouping command is used
as the main result list in the response, using group.format=simple||
  ||group.ngroups||true/false||If true, includes the number of groups that have matched the
query. Default is false.||
+ ||group.truncate||true/false||If true, facet counts are based on the most relevant document
of each group matching the query. Same applies for StatsComponent. Default is false.||
  ||group.cache.percent||[0-100]||If > 0 enables grouping cache. Grouping is executed actual
two searches. This option caches the second search. A value of 0 disables grouping caching.
Default is 0. Tests have shown that this cache only improves search time with boolean queries,
wildcard queries and fuzzy queries. For simple queries like a term query or a match all query
this cache has a negative impact on performance||
