I just checked the roadmap, and I don't see a features that I would really need :
An advanced way of search into search lists where the fields populated should be used directly into search.
For instance, a select list populated with:
blue
red
yellow
Available as the same select list into search / advanced search.
Of course all fields should be searched and combined.
An other feature should be to be allowed to search from SQLqueries fields, and in that case, to be allowed to recreate select lists into the search engine (as the values from the SQLQueries are not contained as tables into the database)
Thanks !
