[jira] [Created] (LUCENE-8882) Add State To QueryVisitor

Atri Sharma created LUCENE-8882:
-----------------------------------

             Summary: Add State To QueryVisitor
                 Key: LUCENE-8882
                 URL: https://issues.apache.org/jira/browse/LUCENE-8882
             Project: Lucene - Core
          Issue Type: Improvement
            Reporter: Atri Sharma


QueryVisitor has no state passed in either up or down recursion. This limits the width of decisions that can be taken by visitation of QueryVisitor. For eg, for LUCENE-8881, we need a way to specify is the visitor is a rewriter visitor.

 

This Jira proposes adding a property bag model to QueryVisitor, which can then be referred to by the Query instance being visited by QueryVisitor.
