Autocard doesn't find a specific card, Sakashima the Impostor

Question

Title. Sakashima the Impostor returns no search result on the gatherer site for some reason. Autocarding Sakashima or Impostor alone at least takes me to the search function that includes the wanted card, but any combination of 2 or all 3 words fails to deliver any result, e.g.

Sakashima the

the Impostor

Sakashima Impostor

Other multi-word autocards function just fine. "Sakashima the Impostor" doesn't even contain special characters or any of the other common autocard failure modes, my language is also set to English.

I noted that there is a Sakashima the Impostor Avatar card, a Vanguard card that is not typically included in search results. Is that the problem? However, that must be a recent change of the search algorithm, because both the regular Sakashima and the Vanguard card are old entries, and in my answer of How to clone a Legendary card legally? I linked Sakashima and it used to work back then.

Test for other Vanguard duplicate names:

Akroma, Angel of Wrath

Arcbound Overseer

Arcanis, the Omnipotent (this goes straight to the avatar page instead of the regular card)

Ashling the Pilgrim

Birds of Paradise

Bosh, Iron Golem

Braids, Conjurer Adept

Chronatog

Dakkon Blackblade

Dauntless Escort

Diamond Faerie

Eight-and-a-Half-Tails

Eladamri, Lord of Leaves

Elvish Champion

Enigma Sphinx

Erhnam Djinn

Etched Oracle

Fallen Angel

Figure of Destiny

Flametongue Kavu

Frenetic Efreet

Goblin Warchief

Grinning Demon

Haakon, Stromgald Scourge

I don't feel like typing all of them out, but you get the idea.

Answer 1

I noted that there is a Sakashima the Impostor Avatar card, a Vanguard card that is not typically included in search results. Is that the problem?

Yep, that's the problem exactly.

When a card name is two or more words, and there is another card that contains that card's name, the search will return no results at all. This is true for "Sakashima the Impostor" because of "Sakashima the Impostor Avatar", and just about every other avatar as you've discovered.

(If it's just one word, e.g. "Island" or "Recall" or the "Chronatog" you found, we're given a search page that includes the card, but not the card's page directly. This is also undesirable.)

There's two current requests to improve our Gatherer search:

• A request to change the Gatherer link formula to another: Can the Autocard feature be improved (again)?. This formula was also proposed in 2014 (actually twice) to fix some issues in autocard v1, but another option was implemented for the current v2.
• The alternative is switching over to a third party MTG search engine: Switch Magic autocard over to a different search engine, Scryfall

The new Gatherer formula resolves our current major problems such as this one. (There are some test cases where it doesn't work quite perfectly in either English or foreign languages.) Scryfall passes all test cases but isn't the official source.
