Simple Search - With Ajax

I need to change the search on the list page to show only the search box, no fields box , no contains box.
If I remove the contains box and change the code to:

add name="SearchOption" value="Contains", it works fine.
When I remove the fields box, it does not give the Ajax search anymore. How do I fix this as the Ajax search in imperative for this specific option.
Lastly, I need the result to open on a whole page (_top). How do I change this. I need to place this code on the homepage and the result needs to open on a whole new page (_top)
Thanks for any help.
Would like to put this on the "wishlist" where the different search boxes would be optional like in other apps. I used previously.
