Description

As described in Wikipedia (http://fr.wikipedia.org/wiki/%C3%89lision), the d character is used in french as an elision character.
E.g.: déclaration d'espèce
So, it would be useful to have it as a default elision token.

ElisionFilter.java

  private static final CharArraySet DEFAULT_ARTICLES = CharArraySet.unmodifiableSet(
      new CharArraySet(Version.LUCENE_CURRENT, Arrays.asList(
          "l", "m", "t", "qu", "n", "s", "j", "d"), true));

HTH
