为什么我在过滤器中使用枚举时在 graphql 中出现语法错误？

Question

For every user has gender property. The gender property is enum in graphql.

I want to query all users that have female and male values only.

Why when I write my query on graphql playground I got an error message?

I also try to write: userMany(filter: { gender: [female, male] }) { but I got syntax error.

Is there another way to write this query to get the results?

The query:

{
  userMany(filter: { gender: female AND male }) {
    name
    age
    gender
    someMixed
    salaryDecimal
    virtualField
  }
}

The error:

{
  "errors": [
    {
      "message": "Syntax Error: Expected :, found Name \"male\"",
      "stack": [
        "Syntax Error: Expected :, found Name \"male\"",
        "",
        "GraphQL request:2:41",
        "1 | {",
        "2 |   userMany(filter: { gender: female AND male }) {",
        "  |                                         ^",
        "3 |     name",

      ]
    }
  ]
}

Try this:

{
  userMany(filter: {OR: [{gender: female}, {gender: male}]}) {
    name
    age
    gender
    someMixed
    salaryDecimal
    virtualField
  }
}
