MongoDB - Can't canonicalize query: BadValue unknown operator: $meta
提问by Sean McClory
This happened to me in 2.6.1 - So, in case anyone wanders into this error, I thought I'd write the answer out.
这在 2.6.1 中发生在我身上 - 所以，如果有人陷入这个错误，我想我会写出答案。
This first command worked fine, but the second one didn't.
第一个命令工作正常，但第二个没有。
db.test.find({$text: {$search: 'york'}} )
db.test.find({$text: {$search: 'york'}, score: {$meta: 'textScore'}} )
and threw up the error below
并抛出下面的错误
{"$err": "Can't canonicalize query: BadValue unknown operator: $meta", "code": 17287}

Turns out I just had the brackets in the wrong place.. and it should have read.
原来我只是在错误的地方放了括号......它应该读过。
//This works
db.test.find(
{ $text: { $search: 'york' } },
{ score: { $meta: 'textScore' } }
);
