The five Refine Search Menus can be used individually or in conjunction with one another. You can choose any, all, or none of the active choices in a menu. To choose a type of refinement, click on the check box next to it. When you have chosen all the refinements you want, click on at the bottom of the list. You can make selections from all of the menus at once if you choose.
If you choose more than one type of refinement in a single category, your Search Result will include all resources from your original search which include any one or more of those choices. For example, if you choose Bibliographies and Lesson Plans from the Learning Aids menu, your result will show all resources from your original search which have EITHER bibliographies OR lesson plans. Of course, some resources may have both.
If you choose refinements from more than one menu, your Search Result will include all resources from your original search which include your chosen results from both menus. For example, if you choose Learning Exercises from the Learning Aids menu and Interactive Media from the Multimedia menu, your final result will show all resources from your original search which have BOTH learning exercises AND interactive media. As you can see, this allows for a great deal of flexibility in the refinement process as you can choose multiple refinements from individual menus AND choose refinements from multiple menus, combining the EITHER/OR results from individual menus with BOTH/AND results from multiple menus.
