To set a target page to display the search results, click the go button.
Under Data near the top of the screen, type in the target page url and click the Set Target Page button. (You can also alter the text "go".)
Set the autocomplete
When a user starts to type in the search box, a list of suggestions will appear. To define them go to Forms and edit the Tags (for search).
You can try to match, or partially match, these values to your facet values. Then they will be highlighted in the filter in the results page, helping users to see what they have searched for and making it easier for them to modify their search.
