Finding reliable search plug-in

I want to replace the default search function with a better one that will show results on the keyword you search for all pages. Right now, it just brings up the post links if a particular keyword is found on the page. We still have to browse through the page to find these keywords.

I tried using the better search plug-in and it’s okay…. not the greatest one to show results. Any thoughts for a reliable search plug-in?
