In this question, the "mtg:Searing Spear" (Searing Spear) doesn't work for me, and it sometimes doesn't for other cards either. It gets me to Gatherer, but it can't find any result, despite correct spelling. It can't be about multiple matches either, because e.g. Lightning also works. Most other cards work fine, including card names with multiple words, such as March of the Machines. I tried with Chrome and Edge, so it's probably not about the browser. Right now I suspect Gatherer as it's been wonky in the recent past, but just to be sure, is there anything on our end that can be done about it?
For example, could someone try to change the url to
i.e. to put every word in its separate pair of brackets, preceded by the + sign?
