• Formulate the question Break your question into
  multiple concepts
• Locate the proper MeSH/thesaurus for each
  concept Use AND to connect different concepts
• Use OR to connect similar concepts
• Refine your search
• Too Many? Apply limit options (language, subset,
  age, publication type, major heading, subheading)
• Too Few? Google Scholar, Scopus
