Factory for
PathHierarchyTokenizer.
This factory is typically configured for use only in the index Analyzer (or only in the query Analyzer, but never both).
For example, in the configuration below a query for Books/NonFic will match documents indexed with values like Books/NonFic, Books/NonFic/Law, Books/NonFic/Science/Physics, etc. But it will not match documents indexed with values like Books, or Books/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/Physics would match documents containing Books/NonFic, Books/NonFic/Science, or Books/NonFic/Science/Physics, but not Books/NonFic/Science/Physics/Theory or Books/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>
