spellchecker: make hard-coded values configurable
-------------------------------------------------

                 Key: LUCENE-852
                 URL: https://issues.apache.org/jira/browse/LUCENE-852
             Project: Lucene - Java
          Issue Type: Improvement
            Reporter: karin


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
environment where the ulimit setting 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,
karin
