Hi,
I use TextIndexNG with french stemmers to index my documents in "full-text" mode. My questions are : - how are TextIndexNG results sorted ?
Sorting is up to the application.
- how are results stored when a TextIndexNG is mixed with other indexes (fieldindexes,...) in a single query ?
same as above (except you specify sort_on on the ZCatalog level)
- is there a "rank" or "score" value available in TextIndexNG query results to be able to sort results manually ?
TextIndexNG does no ranking, ZCTextIndexNG does
- does ZCTextIndex solves these problems ??

ZCTextIndex sorts in reverse order by relevance score (highest first). I think you can also sort by arbitrary indexes if that isn't what you want. It often is (for me at least). Classic TextIndex works this way too, but its scoring algorithm is *much* less sophisticated. hth, -Casey
