  2. 2. Objectives <ul><li>Understand common search syntax </li></ul><ul><li>Use the advanced search functionality of the major search engines </li></ul><ul><li>Compare different Internet search tools and determine which tool is better for a certain search </li></ul>
  3. 3. Power Searching on the Web <ul><li>Jargon terms </li></ul><ul><li>Multiple keywords </li></ul><ul><li>Quotation marks </li></ul><ul><li>OR </li></ul><ul><li>Parentheses </li></ul><ul><li>Limit by site </li></ul><ul><li>Limit by filetype </li></ul><ul><li>+ (plus sign) </li></ul><ul><li>- (minus sign) </li></ul><ul><li>~ (tilde sign) </li></ul>
  4. 4. Power Searching on the Web <ul><li>Jargon terms = Technical terms </li></ul><ul><li>Multiple keywords = Avoid simple search </li></ul><ul><li>Quotation marks = Exact phrase searching </li></ul><ul><li>OR = Concept groupings </li></ul><ul><li>Parentheses = Multiple concept groups </li></ul><ul><li>Limit by site/title </li></ul><ul><li>Limit by filetype </li></ul><ul><li>+ (plus sign) = Stopword searching </li></ul><ul><li>- (minus sign) = Exclude </li></ul><ul><li>~ (tilde sign) = Thesaurus or synonym searching </li></ul>
  5. 5. Tip 1: Use Jargon Terms <ul><li>Specialized or technical terminology </li></ul><ul><li>If the sites we wish to avoid are patient oriented </li></ul>Use language patients wouldn’t understand
  6. 6. Tip 2: Multiple Keyword Search <ul><li>Avoid simple keyword search </li></ul><ul><ul><li>Use at least 3 terms </li></ul></ul>- http://www.keyworddiscovery.com/kd-manual13.html

  10. 11. Tip 4: Boolean OR Results have fewer false negatives.
  11. 12. Tip 5: Concept Group Searching with Parentheses <ul><li>Group terms that should be processed together, at the same time and in the same way in the search </li></ul><ul><li>Want to combine with another concept or term </li></ul><ul><li>Question: Do steroid injections improve shoulder pain? </li></ul><ul><ul><li>Concept 1 = “steroid injections” </li></ul></ul><ul><ul><li>Concept 2 = “shoulder pain” </li></ul></ul><ul><ul><li>Concept 3 = “improve” </li></ul></ul>
  12. 13. Tip 5: Concept Group Searching with Parentheses <ul><li>(“steroid injection&quot; OR cortisone OR depomedrol OR triamcinolone) (improve OR help OR placebo) (“shoulder pain” OR “subacromial impingement” OR “rotator cuff tear”) </li></ul>
  13. 14. Tip 6: Limit by site <ul><li>When you want to control the quality of the search results </li></ul><ul><ul><li>Want government reports on total hip replacement? </li></ul></ul><ul><ul><ul><li>“ total hip replacement&quot; site:fda.gov </li></ul></ul></ul><ul><li>When you know a site that is likely to have what you need </li></ul><ul><ul><li>Want CME on topic from the AAOS, but without using their site search engine? </li></ul></ul><ul><ul><ul><li>CME (&quot;shoulder replacement&quot; OR “shoulder arthroplasty&quot;”) site:aaos.org </li></ul></ul></ul><ul><li>When you want to locate a known document </li></ul><ul><ul><li>Remember a patient guide but not what organization released it? </li></ul></ul><ul><ul><ul><li>(acute back pain OR “acute back pain”) site:.org </li></ul></ul></ul>
  14. 15. Tip 6: Limit by site <ul><li>(“total hip replacement&quot; OR &quot;total hip arthroplasty&quot;) site:clinicaltrials.gov </li></ul>
  15. 16. Tip 7: Limit by filetype <ul><li>When you have reason to suspect that the answer you need will be in a certain format </li></ul><ul><ul><li>white papers, presentations, reprint </li></ul></ul><ul><li>Find a presentation </li></ul><ul><ul><li>((osteonecrosis OR AVN) (hip OR femur OR “femoral head”)) filetype:ppt </li></ul></ul><ul><li>Find a reprint </li></ul><ul><ul><li>((osteonecrosis OR AVN) (hip OR femur OR “femoral head”)) filetype:pdf </li></ul></ul>
  16. 17. Tip 7: Limit by filetype <ul><ul><li>((osteonecrosis OR AVN) (hip OR femur OR “femoral head”)) filetype:ppt </li></ul></ul>
  17. 18. Tip 8: + (plus sign) <ul><li>Google ignores common words and characters such as where, the, how , and other digits and letters </li></ul><ul><li>If a common word is essential to getting the results you want, include it by putting a &quot;+&quot; sign in front of it </li></ul><ul><li>Be sure to include a space before the &quot;+&quot; sign </li></ul><ul><ul><li>ACJ separation type +III </li></ul></ul>
  18. 19. Tip 8: + (plus sign) <ul><li>ACJ separation type +III </li></ul>
  19. 20. Tip 9: - (minus sign) <ul><li>Use the minus sign to exclude terms from results when there is a clustering of irrelevant results </li></ul><ul><li>Help refine a search </li></ul><ul><ul><li>bone-grafting in the treatment of ununited femoral shaft fractures </li></ul></ul><ul><ul><li>nonunion femoral (shaft OR diaphysis) &quot;bone-grafting“ -supracondylar –hip -neck </li></ul></ul>
  20. 21. Tip 9: - (minus sign) <ul><li>nonunion femoral (shaft OR diaphysis) &quot;bone-grafting“ -supracondylar –hip -neck </li></ul>
  21. 22. Tip 10: Use Advanced Search nonunion femoral shaft OR diaphysis &quot;bone grafting&quot; -supracondylar -neck -hip If creating this search string comes naturally, you don’t need Advanced Search
