Subject [jira] [Updated] (LUCENE-3883) Analysis for Irish
Date Tue, 20 Mar 2012 04:29:42 GMT

     [ https://issues.apache.org/jira/browse/LUCENE-3883?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Robert Muir updated LUCENE-3883:
--------------------------------

    Attachment: LUCENE-3883.patch

updated patch, with a simple solution to the hyphen-phrasequery-problem:

I added a special stopset just for these:
{code}
  /**
   * When StandardTokenizer splits t‑athair into {t, athair}, we don't
   * want to cause a position increment, otherwise there will be problems
   * with phrase queries versus tAthair (which would not have a gap).
   */
  private static final CharArraySet HYPHENATIONS = CharArraySet.unmodifiableSet(
      new CharArraySet(Version.LUCENE_CURRENT,
          Arrays.asList(
              "h", "n", "t"
          ), true));
{code}

This is used with enablePositionIncrements=false to ensure no gap is added... I also added
a simple test for this.
