[Sanne Grinovero (JIRA)]

Sanne Grinovero commented on HSEARCH-477:
-----------------------------------------

I assume there might a need to define the order in which TokenFilter(s) and CharFilter(s) are applied?
Maybe filters should be made of type Object, not nice for typesafety and self-documentation, so that it could contain both types.

> 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]
