Boolean Searches
Multiple search terms can be combined using the Boolean operators AND, OR, and NOT. EndNote constructs a search from the top to the bottom of the Search panel, finding the search results of the first two items, then combining that result set with the third search line, and so on.
| Field | Comparison Operator | Search Term | Boolean Operator |
| Keywords | Contains | parrot | AND |
| Keywords | Contains | corvid | NOT |
| Keywords | Contains | avian | OR |
| Keywords | Contains | Emery | |
| Boolean Operators Table | |||
For example, the search shown above could be written as:
(((parrot AND corvid) NOT avian) OR Emery)
First EndNote looks for references about parrots and corvids, then any references to avian would be omitted from that set, and finally all references by Emery would be added.
Keep in mind that:
- OR broadens your search by adding together two result sets
- AND narrows the focus of the search by looking for the intersection of references found
- NOT narrows the search by omitting the results for one term from the current result set.
See A Strategy Tip for the AND, OR, and NOT Operators for an example search strategy to help with using these three operators.
