Subject [jira] Commented: (LUCENE-1938) Precedence query parser using the contrib/queryparser framework
Date Wed, 07 Oct 2009 18:45:31 GMT

Luis Alves commented on LUCENE-1938:
------------------------------------

Hi,

I looked at the pipeline PrecedenceQueryNodeProcessorPipeline, it contains some complex logic
off removing a processor from the StandardQueryNodeProcessorPipeline.

I think it would be better to have a common ancestor, CommonQueryNodeProcessorPipeline, that
both StandardQueryNodeProcessorPipeline and PrecedenceQueryNodeProcessorPipeline can extend.
It should make it easier for people reading the code.
What do you think?
