Support for the new Solr's character filters
--------------------------------------------

                 Key: HSEARCH-477
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-477
             Project: Hibernate Search
          Issue Type: Improvement
          Components: analyzer
            Reporter: Gustavo Fernandes
            Priority: Minor


Solr 1.4 introduced CharacterFilters [1], which are based on Lucene's CharStream. Those filters are currently incompatible with the annotation @TokenFilterDef, which accept only TokenFilterFactories:

{code}
public @interface TokenFilterDef {
	public abstract Class<? extends TokenFilterFactory> factory();
	public abstract Parameter[] params() default { };
{code}

Onde ideia is to keep the same annotation, "generalize" the token filter factory type in the annotation, and on SolrAnalyzerBuilder construct a TokenizerChain which will accept both type of filters [2]
