addProperty

public void addProperty(String name,
                        String text)

Stores and indexes a property in a Document. We don't have to recalculate the concatenated text: just add another TEXT field and Lucene will take care of this. Additional advantage: Lucene may be able to handle the invididual strings in a way that may affect e.g. phrase and proximity searches (concatenation basically means loss of information). NOTE: The TEXT_FIELD_NAME has to be stored, see in LuceneSail
