You may find something, such as a piece of free software that you have been trying to get hold of. I have downloaded many of these myself and use on a regular basis in my everyday computer operating.
You may also find the odd site that you haven't thought of looking up before. There is more than one search engine on the Internet some of which may have slipped your mind or you haven't known they existed. Try some of the others out and read the article about how search engines work, and not only find, but store their information of sites. If you understand this you will understand how to get to grips with more powerful searches than you do at the moment.
Some of the other SeniorNet Sites are worth a visit, while others are quite parochial. These sites can all be accessed from the national site, but why go there when you can do it from one of your own Bookmarks/Favorites?
