Class PathHierarchyTokenizerFactory
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
.
