Open Graves, Open Minds by While creating this guide I discovered that the easiest way to get relevant information about vampires is to always use the search term 'folklore' or 'folktales'. This removes any use of the word vampire as a descriptor. Often, I found that using the advanced search feature and using the NOT boolean operator with the word 'bats' gave me more relevant research as well. Searching the term 'vampire' usually led me to pages about vampire bats, the not supernatural variety,.
