[jira] Commented: (LUCENE-792) PrecedenceQueryParser misinterprets
queries starting with NOT
[ https://issues.apache.org/jira/browse/LUCENE-792?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12477444 ]
Steven Parkes commented on LUCENE-792:
--------------------------------------
Yeah, this was noted by Erik in the svn logs.
Unfortunately, it looks like PQP has been basically dormant (read: undergoing bitrot) since then so not only is NOT precedence not handled, but a lot of other changes that have been made to QP aren't in PQP.
