Subject [jira] Commented: (JCR-1544) [PATCH] fix a NOT b queries
Date Tue, 22 Apr 2008 21:19:21 GMT

Dave Brosius commented on JCR-1544:
-----------------------------------

Ok, fair enough. Is the query syntax of contains documented some where then? It seemed like
it was exactly lucene's syntax except for 'not'. For instance a !b works as expected.

> the query a NOT b doesn't work. Problem was LuceneQueryBuilder was lower casing the NOT
which causes the javacc code to fail.
> In addition, code just did a blind replaceAll on the string "NOT" and "AND", which is
wrong for things like 'BAND'.
> Patch changes code to look for "\\band\\b" -> AND and "\\bnot\\b" -> NOT
