Wikipedia is so vast that the features that usually facilitate navigating, like hypertext and a search box, are supplemented by portals and a page theme that features a toolbox, a search box, and the category of the page, on every page. The category of a page reflects the status of that page in the continuous categorization efforts all pages undergo. Navigation is a critical priority on a Wikipedia page layout. The search box will navigate directly to a page, but this search box is also an interface to a powerful search engine developed especially for Wikipedia. Wikipedia's search box allows readers to apply six different parameters to better refine the search results that a bare word search might produce alone.
