public class PathHierarchyTokenizerFactory extends TokenizerFactory
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...

<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.
