  • 1. Google Advanced & More: The 8-fold Path to Web Searching Power* Patricia F. Anderson October 18, 2007 [email_address] http://www.umich.edu/~pfa/pro/8fold/ © 2007 Regents of the University of Michigan. All rights reserved. * more of what you want, less of what you don’t
  • 2. Power Searching on the Web: Tips
    • Quotation marks
    • OR
    • Parentheses
    • Limit by site
    • Limit by filetype
    • + (plus sign)
    • - (minus sign)
    • ~ (tilde sign)
  • 3. Power Searching on the Web: Tips
    • Quotation marks = Phrase searching
    • OR = Concept groupings
    • Parentheses = Multiple concept groups
    • Limit by site
    • Limit by filetype
    • + (plus sign) = Stopword searching
    • - (minus sign) = Exclude
    • ~ (tilde sign) = Thesaurus or synonym searching
  • 4. Tip 1: Quotation marks for Phrase Searching
    • This is most useful when the words to be searched are not very specific, have different meanings in various subject areas, when having the words adjacent to each other changes the meaning, or when it is important that the same word is repeated.
      • Which works best?
        • catscratch fever
        • “ catscratch fever”
        • breast cancer
        • “ breast cancer”
  • 5. Tip 1: Phrase Searching
    • Results have fewer false positives.
  • 6. Tip 2: OR
    • Use this when you want any of the terms, not all of the terms. Be sure to capitalize the word “or” so Google does not ignore it. Include British and alternate spellings.
      • Child OR children OR youth OR teen OR kids
      • Celiac OR coeliac
      • hemangioma OR haemangioma OR "angioma cavernosum" OR "strawberry mark" OR "stork bite" OR storkbite OR "red birthmarks" OR "birthmarks red"
  • 7. Tip 2: Boolean OR
    • Results have fewer false negatives.
  • 8. Tip 3: Concept group searching with parentheses
    • Useful to group terms that should be processed together, at the same time and in the same way in the search, but which you want to combine with another concept or term.
      • Question: Do sports drinks erode the teeth?
        • Concept 1 = “sports drinks”
        • Concept 2 = “teeth”
        • Concept 3 = “erosion”
  • 9. Tip 3: Concept group searching with parentheses
      • Note: This is most useful with complex questions, questions with many separate concepts, for which initial simple searches provide erratic quality results.
      • EXAMPLE:
        • Question: Do sports drinks erode the teeth?
          • Concept 1 Terms = "sports drinks" OR gatorade OR "isotonic solutions"
          • Concept 2 Terms = dental OR dentistry OR tooth OR teeth
          • Concept 3 = erode OR erosion OR erosive OR "tooth wear” OR caries
  • 10. Tip 3: Concept group searching with parentheses
    • Question: Do sports drinks erode the teeth?
      • Concept 1 Terms = "sports drinks" OR gatorade OR "isotonic solutions"
      • Concept 2 Terms = dental OR dentistry OR tooth OR teeth
      • Concept 3 = erode OR erosion OR erosive OR "tooth wear” OR caries
    • Can you put all those terms on one line like this?
      • "sports drinks" OR gatorade OR "isotonic solutions" dental OR dentistry OR tooth OR teeth erode OR erosion OR erosive OR "tooth wear” OR caries
      • NO!!! There are three different ideas here. If you try this, you will get strange (& probably useless) results because Google won’t be able to tell them apart.
    • Can you search each group separately, and then tell Google to mix and match the results of the 3 searches?
      • I wish, but not yet.
  • 11. Tip 3: Concept group searching with parentheses
    • So what can you do? This -- collect each group of terms by placing parentheses around them to show the beginning and end of a single concept group.
    • Question: Do sports drinks erode the teeth?
      • Concept 1 Terms = ("sports drinks" OR gatorade OR "isotonic solutions”)
      • Concept 2 Terms = (dental OR dentistry OR tooth OR teeth)
      • Concept 3 = (erode OR erosion OR erosive OR "tooth wear” OR caries)
    • Becomes this:
      • ("sports drinks" OR gatorade OR "isotonic solutions") (erosion OR erosive OR "tooth wear") (dental OR dentistry OR tooth OR teeth)
  • 12. Tip 3: Concept group searching with parentheses
    • ("sports drinks" OR gatorade OR "isotonic solutions") (erosion OR erosive OR "tooth wear") (dental OR dentistry OR tooth OR teeth)
  • 13. Tip 3: Concept group searching with parentheses
    • Note: You can use parentheses embedded within parentheses to describe complex concepts or streamline the use of repeated terms.
      • “ baby bottle tooth decay” OR ((“tooth decay” OR caries”) (“baby bottle” OR “early childhood” OR nursing OR milk OR bbtd OR ecc OR toddler))
  • 14. Tip 4: Limit by site
    • This is useful when you want to control the quality of the search results, when you know a site that is likely to have what you need, and also when you want to find again a known document.
      • Want government reports on oral health?
        • "oral health" site:gov
      • Want board review resources from the ADA, but without using their site search engine?
        • (“national boards” OR “board review”) site:ada.org
      • Remember a patient guide but not what organization released it?
        • (mouthguards OR “mouth guards”) site:.org
  • 15. Tip 4: Limit by site
    • (amoxil OR amoxicillin OR trimox or "clavulanate potassium") site:fda.gov
  • 16. Tip 4: Limit by site - inurl variant
    • needlestick (guidelines OR protocol OR "adverse event" OR "critical incident") inurl:med
  • 17. Tip 5: Limit by filetype
    • Especially useful when you have reason to suspect that the answer you need will be in a certain format, such as white papers, presentations, technical standards, and scholarly articles.
      • diabetes diagnosis filetype:pdf
      • "conscious sedation" ("chloral hydrate" OR diazepam OR midazolam) filetype:pdf
      • prevention (“skin cancer” OR “skin neoplasm”) filetype:ppt
  • 18. Tip 5: Limit by filetype
    • (“oral hygiene” OR “oral prophylaxis”) filetype:ppt
  • 19. Tip 6: + (plus sign) = stopword search
    • Use the plus sign to force the inclusion of stop words.
      • Which works best?
        • type i diabetes
        • type +i diabetes
        • "type i diabetes"
        • "diabetes type i"
    • Use this to search foreign words with diacritics exactly as spelled.
      • É mail fragile compared to +émail fragile
  • 20. Tip 6: + (plus sign) = stopword search
    • Émail fragile compared to +émail fragile (phrase means “fragile enamel” in French)
  • 21. Tip 7: - (minus sign)
    • Use the minus sign to exclude terms from results when there is a clustering of irrelevant results. This is most useful when you are new to searching a topic.
      • breast cancer -xxx -porn -pornography -paid
      • “ birth defect” support -teens -youth -parents -child
      • find doctor -site:.com
  • 22. Tip 7: - (minus sign)
    • Demo of effectiveness of quick and dirty porn filter:
      • tongue cancer -xxx -porn -pornography
      • Results without filter = 1,530,000; with filter = 858,000
  • 23. Tip 8: ~ (tilde sign)
    • Searches the selected term in thesaurus-mode (Google only). Results include a variety of related terms.
      • ~child dental visits
  • 24. Tip 8: ~ (tilde sign)
    • Searches the selected term in thesaurus-mode (Google only). Results include a variety of related terms.
      • cancer survivor or ~cancer survivor
  • 25. More Search Strategy Tips
