Description

When using the flexible query parser with the regular expression syntax the processing pipeline fails with the following class cast exception:

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)

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!?
