java - How to return an object with lucene? -

i've been following tutorial on lucene. instead of:

private static void adddoc(indexwriter w, string title, string isbn) throws ioexception {     document doc = new document();     doc.add(new textfield("title", title, field.store.yes));      // use string field isbn because don't want tokenized     doc.add(new stringfield("isbn", isbn, field.store.yes));     w.adddocument(doc); } 

i pass object of own class called car along it's instance variables

private static void adddoc(indexwriter w, car thiscar, string name, string brand) throws ioexception {  document doc = new document(); doc.add(new textfield("name", name, field.store.yes)); doc.add(new stringfield("brand", brand, field.store.yes)); w.adddocument(doc);} 

is there way can search name , brand , have lucene return car object instead of individual string variables? i've looked through docs document class in lucene can't seem find anything.
