[jira] Updated: (LUCENE-1396) Improve PhraseQuery.toString()

["Andrzej Bialecki (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/LUCENE-1396?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Andrzej Bialecki  updated LUCENE-1396:
--------------------------------------

    Attachment: phraseQuery.patch

This patch improves toString(), and adds a unit test.

Gaps are represented as "?" and overlapping terms are separated by a vertial bar sign. Example:

- Query string:
 "hi this is a test"
- Parsed using StopFilter:
 "hi ? ? ? test"
- Added term "hello" at position 1:
 "hi hello ? ? test"
- Added term "hello" at position 0:
 "hi|hello ? ? ? test"

> PhraseQuery.toString() is overly simplistic, in that it doesn't correctly show phrases with gaps or overlapping terms. This may be misleading when presenting phrase queries built using complex analyzers and filters.
