If you use URL components on your item records, URL Component Aliases let you define URL aliases for those items or facets whose URL component you may have changed.

It’s important to remember if you change a URL parameter, it is possible that the page has already been indexed with that URL parameter and also that a visitor may have book marked the page or may have shared the URL with friends. If you change the URL parameter, any search engine that tries to access the page will receive a 404 page not found error.
