The following page has been changed by paulsundling: http://wiki.apache.org/solr/FAQ ------------------------------------------------------------------------------ Performance problems can arise when faceting on fields/queries with many unique values. If you are faceting on a tokenized field, consider making it untokenized (field class `solr.StrField`, or using `solr.KeywordTokenizerFactory`). - Also, keep in mind that Solr must construct a filter for every unique value on which you request faceting. This only has to be done once, and the results are stored in the `filterCache`. If you are experiencing slow faceting, check the cache statistics for the `filterCache` in the Solr admin. If there is a large number of chace misses and evictions, try increasing the capacity of the `filterCache`. + Also, keep in mind that Solr must construct a filter for every unique value on which you request faceting.
