You can combine search lines on the Search panel with the Boolean operators "AND," "OR," and "NOT" to produce the following effects:
AND finds references that match the preceding search line(s) and the following search line. "AND" narrows search results.
Example: A search for "triceratops" AND "extinction" finds only those references that mention both terms.
OR finds references that match either the preceding search line(s) or following search term. "OR" broadens the search.
Example: A search for "triceratops" OR "extinction" finds all references that include either term.
NOT finds all references containing the preceding term(s) and then omits references that contain the subsequent term. "NOT" narrows search results.
Example: A search for "triceratops" Not "extinction" finds all references including "triceratops," excluding any triceratops references that mentioned extinction.
You can use the Boolean operators (AND, OR and NOT) in sequence with as many as nine search lines to build your search strategy.
Items in combination searches are executed from the top field to the bottom field of the Search panel. For example, if you have entered four search lines on the Search panel, EndNote carries out the search by combining the results of the first two items with the third search line. Those results are combined with the fourth search line to produce the final search results.
