Broaden your search

Cast your net wide to ensure you don’t miss any potentially

useful search terms


Narrow your searchMake sure they are the right

nets you’re casting - you only want to return those results

which are most relevant to, let the others “swim free”

butterfly lepidoptera

Using “OR”: butterfly OR lepidoptera


butterfly lepidoptera

… will return all results which include either the term “butterfly” or the term “lepidoptera”, as well as all results which mention both terms.


Most databases assume if you don’t include the “OR” connector, you only want results where

ALL of the terms entered appear.

e.g.

“If you want to search for pages that may have just one of several words, include OR

(capitalized) between the words. Without the OR, your results would typically show only

pages that match both terms”https://support.google.com/websearch/answer/136861?hl=en

Using “AND”: term 1 AND term 2

teenage

abuse”


Using “AND”: teenage AND “substance abuse"

AND


teenage

“substance

abuse”

… will return only those results which include both the term “teenage” and the phrase

“substance abuse”

AND


Some databases will assume an “AND”

between two terms even if you don’t include it...


Some databases will assume an “AND”

between two terms even if you don’t include it...

... but not all.


Examples include:

Power Search: Requires use of ‘AND’ connector. If not included, searches for

terms appearing as a phrase.

Including the ‘AND’ connector “combines search terms so that each

search result contains all of the terms”. Not including runs a search against an account default setting (At Durham, this is “appearing within 5 words of”)http://support.ebsco.com.ezphost.dur.ac.uk/help/

Get in to the habit of using it.
