  • Not is not always an effective search, in that it can sometimes rid you of some valuable sources, so it should be used judiciously. Can be useful when making distinctions between multiple meanings
  • These methods allow the searcher to retrieve results with relevant variations of their search terms. Letters are replaced by characters. These are determined by the database or search engine. Use this carefully – it helps to think of all the alternate words you would want to come up with, and think of these when truncating, so you don’t truncate too much Some databases have their own “stemming” feature where they look for word variations for you.
