| <pre><code> /something/something/else</code></pre> |

| <section><p>Factory for <a class="xref" href="Lucene.Net.Analysis.Path.PathHierarchyTokenizer.html">PathHierarchyTokenizer</a>. |
| <p> |
| This factory is typically configured for use only in the <pre><code>index</code></pre> |
| Analyzer (or only in the <code>query</code> Analyzer, but never both). |
| </p> |
| <p> |
| For example, in the configuration below a query for |
| <code>Books/NonFic</code> will match documents indexed with values like |
| <code>Books/NonFic</code>, <code>Books/NonFic/Law</code>, |
| <code>Books/NonFic/Science/Physics</code>, etc. But it will not match |
| documents indexed with values like <code>Books</code>, or |
| <code>Books/Fic</code>... |
| </p></p> |
| <pre><code><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></code></pre> |
| <p><p> |
| In this example however we see the oposite configuration, so that a query |
| for <code>Books/NonFic/Science/Physics</code> would match documents |
| containing <code>Books/NonFic</code>, <code>Books/NonFic/Science</code>, |
| or <code>Books/NonFic/Science/Physics</code>, but not |
| <code>Books/NonFic/Science/Physics/Theory</code> or |
| <code>Books/NonFic/Law</code>. |
| </p></p> |
| <pre><code><fieldType name="descendent_path" class="solr.TextField"> |
