More advanced facet implementations may compose or subclass this class to leverage any of it's functionality. Inner Class :public static class CountPair implements Comparable<CountPair<K, V>> Field Summary protected  DocSet docs      protected  SolrParams params      protected  SolrIndexSearcher searcher      Constructor Summary public   SimpleFacets(SolrIndexSearcher searcher, DocSet docs, SolrParams params)      Method Summary public  NamedList getFacetCounts()      Looks at various Params to determing if any simple Facet Constraint count computations are desired. public  NamedList getFacetFieldCounts()      Returns a list of value constraints and the associated facet counts for each facet field specified in the params. public  NamedList getFacetQueryCounts()      public  NamedList getFacetTermEnumCounts(SolrIndexSearcher searcher, DocSet docs, String field, int offset, int limit, int mincount, boolean missing, boolean sort, String prefix)      Returns a list of terms in the specified field along with the corresponding count of documents in the set that match that constraint. public static  NamedList getFieldCacheCounts(SolrIndexSearcher searcher, DocSet docs, String fieldName, int offset, int limit, int mincount, boolean missing, boolean sort, String prefix)      Use the Lucene FieldCache to get counts for each unique field value in docs. public static  int getFieldMissingCount(SolrIndexSearcher searcher, DocSet docs, String fieldName)      Returns a count of the documents in the set which do not have any terms for for the specified field. public  NamedList getTermCounts(String field)      Field Detail docs protected DocSet docs(Code) The main set of documents all facet counts should be relative to params protected SolrParams params(Code) Configuration params behavior should be driven by searcher protected SolrIndexSearcher searcher(Code) Searcher to use for all calculations Constructor Detail SimpleFacets public SimpleFacets(SolrIndexSearcher searcher, DocSet docs, SolrParams params)(Code) Method Detail getFacetCounts public NamedList getFacetCounts()(Code) Looks at various Params to determing if any simple Facet Constraint count computations are desired.

The field must have at most one indexed token per document. getFieldMissingCount public static int getFieldMissingCount(SolrIndexSearcher searcher, DocSet docs, String fieldName) throws IOException(Code) Returns a count of the documents in the set which do not have any terms for for the specified field.
