Google searches and the plus sign
The Google search syntax accepts a plus sign in front of a search term. There are two situations where you might want to do this.
Firstly, a plus sign tells Google that you really truly honestly do want to search for a common term. A simple search for book a love returns mostly results that contain the more common phrase “Book of Love”.
Searching for book +a love fixes this; so does searching for “book a love” if you want the words to appear in that order - because common terms within a phrase are always matched.
A second use of the plus sign is to tell Google not to mess with your search term. A search for well yields a page cluttered with results for Wells Fargo, whereas these are absent from a search for +well.
The plus sign is not a search operator that I would use often, but just occasionally it’s a useful tool to get some unwanted entries off the search results list.
