This search was done in the Advanced Search page. You'll notice that there are two lines of search terms with "OR" between the lines. This way we get all the items that have Afro-Latin* (remember the * gives alternate endings) where people used a hyphen. We also get all of the items where the author did not use a hyphen (afrolatinidad, for example). By combining these two similar ways of referring to the concept with the term OR we can get more results with one search.
