Hi,
Hibernate Search does not have any additional support in form of additional annotations or the like. However, lexemes and stopwords are normally handled on the analyzer level. You can either implement your own custom analyzer for this or utilize the extensive Solr analyzer factories which can be used in Hibernate Search via the @AnalyzerDef annotation. Check the online documentation for that.
We are also talking about adding a spell checking API to Hibernate Search (
http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-269), but I think that is not what you mean here.
