Package org.apache.lucene.analysis.path
Class PathHierarchyTokenizerFactory
java.lang.Object
org.apache.lucene.analysis.AbstractAnalysisFactory
org.apache.lucene.analysis.TokenizerFactory
org.apache.lucene.analysis.path.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
.
