I don't understand why so many websites and services do this; it's really silly.
On 4chan, various trolls love to make topics that test the definition to see if they are removed by being very technical with it.
I also tried trace.moe on The Wonderful Adventures of Nils, which is one of the most commercially successful “anime” of all time and it produced no results. So as the title suggests, perhaps it's one of those websites that says “anime”, where it actually simply means “moe art”.
The FAQ says they've indexed most of post-2000 anime and very little of 80s and 90s anime. It mentions you can even use a similar drawing of the scene to get a match, due to the method they're using!
I simply quæstion the sanity of delimiting the search to animated works from a single country, and as I pointed out since it can't find something from Nils, it isn't really about that.

It also couldn't find anything from The Spirits Within and Advent Children, so it's really not about “animation from Japan” but about specific art styles, it seems.
Yes, the one colloquially known as anime.
If “moe art” be what one means, then simply use that word; — there is already a perfectly good word for it.
Feel free to popularize it on its merits first, then we can talk.
