Thread:Project:Support desk/$wgVectorUseSimpleSearch = false; Does not result in two (Go and Search) buttons after upgrading to 1.23.1/reply (3)

I currently don't know of an option to do so. Technically the "Search" button is removed from output by some jQuery JavaScript. I think the class or ID, based on which this happens was called "searchPlaceholder" or something like that. You will be able to see it in the file skins/Vector.php where the searchbox is defined; that is rather at the bottom of that file. You might be able to change this behaviour by adding according code to the page MediaWiki:Common.js in your wiki.
