---------------------------------------
Summary: AnalyzerQueryNodeProcessor throws a class cast exception
with the RegexpQueryNode
Key: LUCENE-4103
URL: https://issues.apache.org/jira/browse/LUCENE-4103
Project: Lucene - Java
Issue Type: Bug
Components: core/queryparser
Reporter: Daniel Truemper
Priority: Minor
When using the flexible query parser with the regular expression syntax the
processing pipeline fails with the following class cast exception:
{noformat}
java.lang.ClassCastException:
org.apache.lucene.queryparser.flexible.standard.nodes.RegexpQueryNode cannot be
cast to org.apache.lucene.queryparser.flexible.core.nodes.FieldQueryNode
at
__randomizedtesting.SeedInfo.seed([34AF003D9388DF45:CB5F8BB4EE483FEE]:0)
at
org.apache.lucene.queryparser.flexible.standard.processors.AnalyzerQueryNodeProcessor.postProcessNode(AnalyzerQueryNodeProcessor.java:114)
{noformat}
A very simple patch is attached that will simply add the RegexpQueryNode to the
nodes that should not get processed by the AnalyzerQueryNodeProcessor. I think
this means that the regular expression is not analyzed, which should be ok!?
