      Description

      the class org.apache.lucene.search.spell.SpellChecker uses the following hard-coded values in its method
      indexDictionary:
      writer.setMergeFactor(300);
      writer.setMaxBufferedDocs(150);
      this poses problems when the spellcheck index is created on systems with certain limits, i.e. in unix
      environments where the ulimit settings are restricted for the user (http://www.gossamer-threads.com/lists/lucene/java-dev/47428#47428).

      there are several ways to circumvent this:
      1. add another indexDictionary method with additional parameters:
      public void indexDictionary (Dictionary dict, int mergeFactor, int maxBufferedDocs) throws IOException

      2. add setter methods for mergeFactor and maxBufferedDocs
      (see code in http://www.gossamer-threads.com/lists/lucene/java-dev/47428#47428 )

      3. Make SpellChecker subclassing easier as suggested by Chris Hostetter
      (see reply http://www.gossamer-threads.com/lists/lucene/java-dev/47463#47463)

      thanx,
