Can someone explain to me how to use "SEARCH"

As a human with commonsense, NEVER THOUGHT THAT I WILL NEED TO EVEN ASK THIS.... 

Why LEFT clicking on the searched result will not open anything? 

I only manage to open the search result by RIGHT clicking → preview 

And then, Click on the button that was BLOCKED by the interface 


DO I NEED TO STICK MY ELBOW IN MY EAR AND PLACE MY KNEE BEHIND MY BACK AND THEN DO THESE MOUSE CLICKS WHEN USING THIS PLATFORM AND HOPE IT WORKS?
