QueryParser replacing stop words with wildcards
-----------------------------------------------
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
