fix wrong facet method in description

  
  First, the filter cache stores the results of any filter queries ("fq" parameters) that
Solr is explicitly asked to execute. (Each filter is executed and cached separately. When
it's time to use them to limit the number of results returned by a query, this is done using
set intersections.)
  
- Second, the filter cache is used for faceting in some cases. (In particular, when the TermEnum
method is used, a filterCache entry is added for each term tested.)

  Finally, the filter cache may be used for sorting if the <useFilterForSortedQuery/>
config option is set to true in solfconfig.xml.
  
- If you use faceting with the fieldCache method (see SolrFacetingOverview), it is recommended
that you set the filterCache size to be greater than the number of unique values in all of
your faceted fields.
