We should do one of A) disallow these hints, B) ignore the hints, C) (somehow) make them produce the correct query results. I strongly prefer option A or B with a slight preference for A over B.
> db.foo.insert({a:1})
WriteResult({ "nInserted" : 1 })
> db.foo.createIndex({x: '2d'})
{
"numIndexesBefore" : 1,
"numIndexesAfter" : 2,
"createdCollectionAutomatically" : false,
"ok" : 1
}
> db.foo.createIndex({x: '2dsphere'})
{
"numIndexesBefore" : 2,
"numIndexesAfter" : 3,
"createdCollectionAutomatically" : false,
"ok" : 1
}
> db.foo.createIndex({x: 'text'})
{
"numIndexesBefore" : 3,
"numIndexesAfter" : 4,
"createdCollectionAutomatically" : false,
"ok" : 1
}
// finds a doc
> db.foo.find({a:1})
{ "_id" : ObjectId("61d1143d15ce86cd9a31d385"), "a" : 1 }
// None of these find the doc
> db.foo.find({a:1}).hint({x: '2d'})
> db.foo.find({a:1}).hint({x: '2dsphere'})
> db.foo.find({a:1}).hint('x_text')

I didn't test with "somewhat special" indexes like partial indexes or filtered indexes, but they may have the same issue.
