Erick Erickson resolved LUCENE-373. ----------------------------------- Resolution: Won't Fix 2013 Old JIRA cleanup > Query parts ending with a colon are handled badly > ------------------------------------------------- > > Key: LUCENE-373 > URL: https://issues.apache.org/jira/browse/LUCENE-373 > Project: Lucene - Core > Issue Type: Bug > Components: core/queryparser > Affects Versions: 1.4 > Environment: Operating System: Windows 2000 > Platform: PC > Reporter: Andrew Stevens > Priority: Minor > Labels: newdev > > I'm using Lucene 1.4.3, running > Query query = QueryParser.parse(queryString, "contents", new > StandardAnalyzer()); > If queryString is "search title:" i.e. specifying a field name without a > corresponding value, I get a parsing exception: > Encountered "<EOF>" at line 1, column 8. > Was expecting one of: > "(" ... > <QUOTED> ... > <TERM> ... > <PREFIXTERM> ... > <WILDTERM> ... > "[" ... > "{" ... > <NUMBER> ... > If queryString is "title: search", there's no exception. However, the parsed > query which is returned is "title:search". If queryString is "title: > contents: > text", the parsed query is "title:contents" and the "text" part is ignored > completely. When queryString is "title: text contents:" the above exception > is > produced again. > This seems inconsistent. Given that it's pointless searching for an empty > string (since it has no tokens), I'd expect both "search title:" & "title: > search" to be parsed as "search" (or, given the default field I specified, > "contents:search"), and "title: contents: text" & "title: text contents:" to > parse as "text" ("contents:text") i.e. parts which have no term are ignored. > At > worst I'd expect them all to throw a ParseException rather than just the ones > with the colon at the end of the string. -- This message was sent by Atlassian JIRA (v6.1#6144) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
