A scoped search let's you limit the results to a particular domain pattern.
For this example we will be searching the larger VCU Meta collection for all pages that include the pattern "dentistry.vcu.edu/about." This is a silly example, but hopefully it demonstrates the usefulness of this parameter.
Try searching for the terms "Richmond", "Strategic plan" or "!noshow."
Just for demonstration purposes, try changing the value of the scope input to just "about." This will pull back results from the larger vcu-meta collection for every page that has "about" in the url path.
