Online Searching Techniques
Boolean Operators Phrase Searching Truncation / Wildcard Searching Proximity Searching Focusing / Limiting a Search
![Page 24: 1 Use of Electronic Resources in Research Prof. Dr. Khalid Mahmood Department of Library & Information Science University of the Punjab](https://reader035.vdocument.in/reader035/viewer/2022062511/5514a516550346b2598b5cd9/html5/thumbnails/24.jpg)

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.

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”

27
Truncation / Wildcard SearchingThese 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.

28
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

Focusing / Limiting a SearchThere 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
