Elasticsearch post_filter

Question

Is there any way to apply multiple conditions to the post_filter in elasticsearch?

GET /job/_search
{
  "post_filter":
      {
        "terms": {
          "expertise_level": [
            "medium",
            "high"
          ]
        }
      },
    "aggs": {
      "expertise_level": {
        "terms": {
          "field": "expertise_level",
          "size": 10
        }
      }
    }
}

This will work. But I want to add multiple filters to the query. How can I achieve this??

Use bool clause:

{
"post_filter": {
  "bool": {
     "must": [
        {
          //Add  Filter 1
        },
        {
          //Add  Filter 2
        },
        {
           //Add  Filter 3
        }
     ]
     }
   }
}
