  • 13. Phrase SearchingIt narrows your search down by searching for an exact phrase or sentence. It is particularly useful when searching for a title or a quotation. Usually quotation marks are used to connect the words together.For example“Towards a healthier Scotland” 13
  • 14. Truncation / WildcardThese search techniques retrieve information on similar words by replacing part of the word with a symbol usually a * or ?. However, different databases use different symbols, so check what is used. In truncation the end of the word is replaced.  For example physiother* will retrieve physiotherapy, physiotherapeutic, physiotherapist and so on. In wildcard searching, letters from inside the word are replaced.  For example wom*n will retrieve the terms woman and women. 14
  • 15. Proximity SearchingIt looks for documents where two or more separately matching term occurrences are within a specified distance, where distance is the number of intermediate words or characters For example  Term A NEAR Term B  Term A ADJ Term B 15
  • 16. Focusing / Limiting a SearchThere are many ways to focus your search and all search tools offer different ways of doing this.
