Use the Search panel to find all references that contain a particular term:
Display All References to make sure you are searching your entire library.
From the Tools menu, select Search Library (Ctrl
+F).
Set the search field to Any Field and the Comparison list to Contains.
Type the desired text into the first search line.
Click Search to begin the search.
If no references in the library match your search request, EndNote displays "No matching references found." Otherwise, all matching references are displayed in the Library window.
When you are finished working with the found references, click the All References group or select Show All References (Ctrl +Shift+M) from the References menu to restore all references to view or start another search.
After completing a search, EndNote displays the same library that you were viewing before the search. However only the references that match your search requests are showing.
The references found in the last search operation are saved in a temporary Search Results group. Each time you run a search, the temporary Search Results group is updated with the new set of references. When you close the library, this temporary group is discarded.
