Your search results will appear as thumbnail images.  If you click on the thumbnail you will get a full screen version of the image and the full caption.  This larger image is displayed in the context of the gallery that contains it, where it could be one of several thousand images!  Moving to the next or previous full screen image will take you to the next or previous image in the gallery, which may not be relevant to your search. 

To get back to your search results, use the back button of your web browser, not the left pointing back arrow that is top left in the Zenfolio window.
