Indexes in KM search Iview --> dont want to appear all

Hi,

I make a KM search Iview and give into it search component set (with search_input_indexes) and options set (with a Search Index ID and Index Group), then run the page with the Iview but in the combo box appear all index of my system that are active but I don't want this, I only want the indexes that i put in the search option set.

I also tried to put SearchType=ctrlpers in the query parameter but it doesn't work.

Any clue?

Thanks in advance.
