Demonstration of [Lookup Patterns: Uncertain Category](https://ant.design/docs/spec/reaction#Lookup-Patterns).

```tsx

  return Math.floor(Math.random() * (max - min + 1)) + min; // eslint-disable-line no-mixed-operators
}

const searchResult = (query: string) => {
  return new Array(getRandomInt(5))
    .join('.')
    .split('.')
    .map((item, idx) => {
      const category = `${query}${idx}`;
      return {
        value: category,
