[Zope] Sorting TextIndexNG results...

[Thierry FLORAC]

  Hi,

I use TextIndexNG with french stemmers to index my documents in "full-text" 
mode.
My questions are :
 - how are TextIndexNG results sorted ? 
 - how are results stored when a TextIndexNG is mixed with other indexes 
(fieldindexes,...) in a single query ?
 - is there a "rank" or "score" value available in TextIndexNG query results 
to be able to sort results manually ?
 - does ZCTextIndex solves these problems ??

Thanks,

  Thierry
