AND: Searches for items containing Both search terms:
So you'd see only articles mentioning BOTH Elephants and Africa. This is your go-to for most searches, and narrows your results
NOT: Removes a term from a search that keeps coming up
So you'd find articles about elephants, but none that mention Africa. NOT Booleans are great for removing false positives (Utah AND jazz NOT Basketball)
OR: Searches for either search term, regardless whether they both appear together
So this would give you sources on either Africa or Elephants, regardless of whether they were used together. OR Booleans are great for synonyms (Bigfoot OR Sasquatch)
