By default, Google searches all the words you enter. However, sometimes you may want to search for one or the other. You can do that by using the OR command. For example, if you do not know whether you want to go hiking in the mountains of Switzerland or France. You then add Switzerland OR France to your search query. Please note that OR must be capitalised. Preferably use brackets to clarify your search. Like hiking (Switzerland OR France) or to make it even more complicated (hiking OR cycling) (camping OR hotel) (Switzerland OR France). By the way, instead of OR you can also use |, i.e. the vertical line, also called pipeline.
