Most browsers make it easy for you to open a search engine of some sort. Look about for the word search on the browser screen.
Most browsers try to make it easy to begin a search.
Despite the fact that browsers vary and new versions are regularly released, I have faith they will be designed not to frustrate you. You will quickly find that searching for the right site can be a little tricky. The possible number of sites at the time I did that search totaled over 51 million separate Web sites. This time you should come up with around 33,000 or so. You can narrow it even further if you need to.
