Hello,
I have  3 questions:
1.      If the search  has no success, it shows a blank screen. It is possible to add a message like: Sorry your search has no result…?
2.      Is it possible combine a search keywords (AND, OR…) ? where I can find a guide?
3.      If I’m already in a category, is it possible to filter and have a search restricted to that category only?
 
Hope you can help me
Thank you
