How to Search in the Health Sciences: Truncation

Truncation basics

  • Truncation is used with root words to express multiple endings
    • Example: 
      • cold*
      • would find cold, colder, coldest
  • Wildcards are used within words to find words spelled differently but have the same meaning,
    • Example:
      • labo?r
      • would find labor or labour
  • Truncation and wildcards vary from database to database. Check the database Help page to find out what to use in your search.
  • Common truncation/wildcard symbols include: *, #, ?, $, !. You must find what symbol each database uses and how they use that symbol, you may not be getting the results you expect if you don't do this.

Warning: when using truncation make sure to use enough of the root word to express your idea, use too little and you will get bad results.
