RH 11: how to stop index from re-loading after an index term is selected?

I am using the Responsive HTML5 layout in Robohelp 11. When using the Index search, the index re-loads after a user selects an index term. This deletes the search term just entered and refreshes the index back to it's default (starting at 'A'). My users have complained about this change from RH 9 Webhelp, because if they accidentally click the wrong term, they have to re-enter their search term. In RH 9 Webhelp, the search term just entered would stay in the index search field after a term was clicked, so that a user could easily click an adjacent term if they mis-clicked.

Is there a way to stop the index from re-loading/refreshing after an index term is clicked in Responsive HTML5?
