Saved filter - OR operator

[antkachenko]

Dear colleagues,

I'm trying to create filter that will show me all records marked by tags "1" and "2". Using the following request no records being returned:

{
"tag": [
"1",
"2"
]
}

As I understood what's becouse it searches for the records with both tags. But for the second variant it returnes all records including those have no tag at all.

{
"$or": [
{"tag": "1"},
{"tag": "2"}
]
}

What am I doing wrong?
