public class PathHierarchyTokenizerFactory extends TokenizerFactory
Factory forPathHierarchyTokenizer.This factory is typically configured for use only in the
indexAnalyzer (or only in thequeryAnalyzer, but never both).For example, in the configuration below a query for
Books/NonFicwill match documents indexed with values likeBooks/NonFic,Books/NonFic/Law,Books/NonFic/Science/Physics, etc. But it will not match documents indexed with values likeBooks, orBooks/Fic...<fieldType name="descendent_path" class="solr.TextField"> <analyzer type="index"> <tokenizer class="solr.PathHierarchyTokenizerFactory" delimiter="/" /> </analyzer> <analyzer type="query"> <tokenizer class="solr.KeywordTokenizerFactory" /> </analyzer> </fieldType>In this example however we see the oposite configuration, so that a query for
Books/NonFic/Science/Physicswould match documents containingBooks/NonFic,Books/NonFic/Science, orBooks/NonFic/Science/Physics, but notBooks/NonFic/Science/Physics/TheoryorBooks/NonFic/Law.<fieldType name="descendent_path" class="solr.TextField"> <analyzer type="index"> <tokenizer class="solr.KeywordTokenizerFactory" /> </analyzer> <analyzer type="query"> <tokenizer class="solr.PathHierarchyTokenizerFactory" delimiter="/" /> </analyzer> </fieldType>- Since:
