Breadcrumbs
Breadcrumbs are a navigation technique used in web sites. The purpose is to give users a way to keep track of their location and provide a trail to follow back to the starting/entry point.

Tips
Each time you click on
a content type or related category navigator, the results returned will
be a subset of the previous results. Only companies or products that satisfy
all of the criteria in the breadcrumb will return results. This
helps you drilldown to their exact requirement.
Example: Searching
on the term luminescent returns 10 results as shown above. Then
selecting CAD & catalog narrows down the result set to one company
Zero International. This
company is the only one that satisfies the search term and contains both
content types CAD & catalog.
