  1. search engines
    information retrieval systems that search the internet and electronic databases for websites, files, or documents based on keywords or phrases.
  2. databases
    organized systems that allow search access for specific content or information

    NOTE: pg 742-48 gives 17 bolded databases telling you what they are. For example CINAHL is a nursing journal. I figured it would be easier during the test to know where these are located --> waste of penguin space and space on paper lol ).
  3. Boolean Logic
    The use of words of AND, OR, and NOT as logical operators when searching databases.

  4. exploding
    to explode research (lol!) means that the research will retrieve results using the selected term and all of the more specific terms in the tree

  6. limits or filters

  7. truncation or wildcard
    symbols that databases recognize that can be used to allow a broad interpretation of a search term, finding plurals, spelling variations and alternate forms of words
  8. recall
    aka sensitivity, is the proportion of retrieved citations that are relevant, or the likelihood of finding relevant references; may include irrelevant studies but are more comprehensive
  9. precision
    aka specificity; is the proportion of citations that are relevant that the search is able to retrieve, or the likelihood of excluding irrelevant references. This may exclude some relevant studies but is more likely to include the very relevant ones.
  10. PICO (pg 755 for a good example 2nd green box)
