The '''Browser-based Search''' control affects how this Yioop installation offers itself to a web browser as one of the search engines that browser can use from its own search box or address bar. It does not change how any page of this site looks or how a search on this site behaves.

'''Search Toolbar''' is the description file a browser reads to learn about this site's search. It is a small XML file naming the site and giving the pattern of URL a browser should use to run a search here. A browser that has read it can offer this site in its own list of search engines, so that someone can search this site from the browser without coming to the site first. Yioop serves a description of its own at yioopbar.xml, and uploading a file here has the site name that file instead.

The upload only takes XML; a file of any other type is turned away, as is a file larger than the size shown next to the control. A browser reads a description once and remembers it, so after changing this file a browser that already knows this site may go on using what it read before until it is asked to look again.

This setting belongs to the whole installation rather than to one domain. A browser keeps the search engines it knows in a list of its own rather than per site, so one description is what names this site to it. If this installation answers on several domains, they share the toolbar set here.
