AND only returns search results that contain both keywords
- A search for "amphibian" AND "pollution" includes only results that contain both keywords
OR returns results that include either keyword
- A search for "amphibian" OR "pollution" includes results with either of those keywords
NOT excludes one or more of your keywords
- A search for "amphibian" NOT "pollution" will include results that contain the keyword “amphibian” but not "pollution"
It can also be helpful to combine Boolean Operators while searching. By using two Boolean operators in a search, it is possible to do a broad search for one set of terms and a narrow search for another at the same time to get more specific results.
A few sample searches for this would be:
(Dog OR Canine) AND (Origins AND Ancestry)
(Dog OR Canine) will search for the terms "dog", "canine", and "dog or canine", which makes it a broad search. (Origins AND Ancestry) will search "origins and ancestry" together, but not each on their own. By searching these together, the results will include anything about dogs, canines, dogs and canines in the context of origins and ancestry.
(Avian OR Bird) AND (Climate And Environment)
(Avian OR Bird) AND (Climate AND Environment) will select articles about "avians", "birds", and "avians or birds", which is the broad search. (Climate AND Environment) will select articles about "climate and environment" together, but not on their own as well. By searching these together, the results will include anything about birds, avians, avians or birds, but only those articles which also include climate and environment as other topics/keywords.
If you’re coming up with too few or too many results, try these tips!
Broaden your search
• Shorten a word to its root (truncate it) and add an asterisk (*)
◦ A search for pollut* would include the words pollute, pollution, pollutant, pollutants...
• Use OR instead of AND between keywords
Narrow your search
• Use AND between keywords
• Use NOT to exclude keywords
