Andi Vajda commented on PYLUCENE-9:
-----------------------------------
So I wrote this simple class, foo:
import org.apache.lucene.analysis.standard.StandardAnalyzer;
import org.apache.lucene.queryParser.QueryParser;
import org.apache.lucene.queryParser.ParseException;
import org.apache.lucene.util.Version;
public class foo {
static void parse(Version version)
throws org.apache.lucene.queryParser.ParseException
{
System.out.println(
version + " " +
new QueryParser(version, "ft", new StandardAnalyzer(version))
.parse("\"Calendar Item as Msg\""));
}
static public void main(String[] args)
throws org.apache.lucene.queryParser.ParseException
{
parse(Version.LUCENE_24);
parse(Version.LUCENE_29);
parse(Version.LUCENE_30);
parse(Version.LUCENE_CURRENT);
}
}
I then compiled it against the lucene-3.0.3 jar:
$ javac -cp lucene-java-3.0.3/build/lucene-core-3.0.3.jar foo.java
and then ran it against the same jars:
$ java -cp lucene-java-3.0.3/build/lucene-core-3.0.3.jar:. foo
LUCENE_24 ft:"calendar item msg"
LUCENE_29 ft:"calendar item ? msg"
LUCENE_30 ft:"calendar item ? msg"
LUCENE_CURRENT ft:"calendar item ? msg"
As you can see, the same behavior is seen without PyLucene, just plain java.
The parsing behavior you expect seems to happen only with Version.LUCENE_24.
Please, send java code (as PyLucene seems out of the picture for now), that
reproduces the problem.

> Key: PYLUCENE-9
> URL: https://issues.apache.org/jira/browse/PYLUCENE-9
> Project: PyLucene
> Issue Type: Bug
> Environment: Windows XP 32-bit Sp3, Ubuntu 10.04.2 LTS i686
> GNU/Linux, jdk1.6.0_23
> Reporter: Christopher Currens
>
> Was using query parser to build a query. In Java Lucene (as well as
> Lucene.Net), the query "Calendar Item as Msg" (quotes included), is parsed
> properly as FullText:"calendar item msg" in Java Lucene and Lucene.Net. In
> pylucene, it is parsed as: FullText:"calendar item ? msg". This causes
> obvious problems when comparing search results from python, java and .net.
> Initially, I thought it was the Analyzer I was using, but I've tried the
> StandardAnalyzer and StopAnalyzer, which work properly in Java and .Net, but
> not pylucene.
> Here is code I've used to reproduce the issue:
> >>> from lucene import StandardAnalyzer, StopAnalyzer, QueryParser, Version
> >>> analyzer = StandardAnalyzer(Version.LUCENE_30)
> >>> query = QueryParser(Version.LUCENE_30, "FullText", analyzer)
> >>> parsedQuery = query.parse("\"Calendar Item as Msg\"")
> >>> parsedQuery
> <Query: FullText:"calendar item ? msg">
> >>> analyzer = StopAnalyzer(Version.LUCENE_30)
> >>> query = QueryParser(Version.LUCENE_30)
> >>> parsedQuery = query.parse("\"Calendar Item as Msg\"")
> >>> parsedQuery
> <Query: FullText:"calendar item ? msg">
> I've noticed this in pylucene 2.9.4, 2.9.3, and 3.0.3
