Development of Search Strategies

• 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? Explode

My NCBI Features

• Highlight PubMed search words in your retrieval
• Set Abstract format on MyNCBI account
• to open the supplemental data (MeSH, PTs)

10
PubMed Quick TipsWhen you get too many results,
try these tips.

• Use quotation marks to search on a phrase
• Use tiab to find a word/phrase in the title or
  the abstract
• Use ti to find a word/phrase in the title
• Use to find alternative endings (childgt
  child, children, childbearing)

  types) from Advanced Search page to narrow your
  search

  articles CINAHL can use peer-reviewed limiter
  or use journal subset peer-reviewed to locate
  peer-reviewed articles
