I have 1000 documents with 5 categories. Each category has around 200 documents. I want to pull 30 random documents with at-least 5 from each category. Please suggest me any solution.

[Random Score](https://www.elastic.co/guide/en/elasticsearch/guide/current/random-scoring.html)?

```
{
    "size": 5,
    "query": {
        "function_score": {
            "functions": [{
                "random_score": {
                    "seed": "1518707649"
                }
            }]
        }
    }
}

```

Make sure to use a different seed for each query (you can use the current timestamp).
