Indexing option, luceneSearch sort option

I have the question:1) in the WiKi (http://wiki.alfresco.com/wiki/Full-Text_Search_Configuration) we have this info:The indexing behaviour of each property can be set in the content model. By default, they are indexed atomically. The property value is not stored in the index, and the property is tok

Hi

It is possible to order at the moment it just will not always be right (as it will use the tokens - so anything containing any token starting with "a" will be near the top …).
In some cases lucene may complain.

This is a trade off between FTS search and ordering.
In later versions we support FTS and ordering for some properties (like name). Then ordering and FTS will both be correct.

There are now more options for tokenisation in the property definition in the data dictionary.
"both" supports ordering and FTS.

Thank you Andy for your answer.

But we have encountered with these two questions:
1) What is the best/fastest method to correctly sort lucene results by properties that contain multiple tokens? Is the only choice to sort "manually" in the web script after running the lucene query without sorting?

2) Can you tell us more specifically which versions when you said "In later versions we support FTS and ordering for some properties (like name)"?
