EndNote’s search interface provides a simple way to do basic searches on EndNote libraries and online databases. The same Search panel is used for both purposes.
This search interface is not intended to replace the advanced search options that may be available using the search interface offered by your information provider. There may be times when you want to use the information provider’s search interface (for example, to take advantage of a thesaurus of search terms) and then import those references into EndNote. This is still an option using EndNote’s Import command (see Importing Reference Data into EndNote). But once you know the terms that you want to use in your searches, being able to retrieve the necessary references directly from EndNote is a very fast and efficient approach.
