public static Analyzer createPerFieldEntityAnalyzer(Class indexFieldClass) {
    PerFieldAnalyzerWrapper wrapper = new PerFieldAnalyzerWrapper(new
StandardUnaccentAnalyzer());

    for(Object o : EnumSet.allOf(indexFieldClass)) {
        IndexField indexField = (IndexField) o;
        Analyzer analyzer = indexField.getAnalyzer();
        if (analyzer != null) {
            wrapper.addAnalyzer(indexField.getName(), analyzer);
        }
    }

    return wrapper;
}
