You may find that you have too much page content to ideally fit a single page. Rather than creating a series of child pages, however, you can include a Page Navigation Toolbar that allows you to tab between content on a single page.
Incorporating search bars can be difficult and often lead you making sacrifices to shove new input elements into your design. With a search bar that replaces your top navigation, however, you can direct user behavior while maintaining the consistency of your design.
