10 10 Online Searching Techniques Boolean Operators Phrase Searching Truncation / Wildcard Searching Proximity Searching Focusing / Limiting a Search

11 11 Boolean Operators AND OR NOT Boolean operators allow you to join terms together, widen a search or exclude terms from your search results. This means you can be more precise in locating your information.

13 13 Phrase Searching It 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

14 14 Truncation / Wildcard These 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.

15 15 Proximity Searching It 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

16 16 Focusing / Limiting a Search There are many ways to focus your search and all search tools offer different ways of doing this. Some of the ways of limiting your search are as follows: Date Language Place Publication type Age groups Type of material e.g. you could just need to find case studies
