I have a search center used by other web applications and site collections. When the users lands on the search site they make a couple of more searches or they go to search site home page by clicking the logo.
I need to place a link or a button that brings them back to the referring site. What is the best way to achieve this?
Pass the query string parameter as 'source' when you navigate to search center from source site cillection. Like https://scenter/page.aspx?source=encodedsitecollurl. Add a link in your search center page. Get the source parameter value using ootb js function GetUrlKeyVal('source') in search page and assign the value as href to anchor tag.
