Using term query with Or operator

Question

I am trying to use the term query the following way!!

{
  "query": {
    "bool": {
      "must": [
        {
          "term": {
            "technology": "Space"
          }
        },
        {
          "term": {
            "Person": "Steve Simon"
          }
        }
      ]
    }
  }
}

Which returns me a response of feeds which has both fields present in single feed like an intersection operation. Can I use the term query to get UNION result for the above query like, I want all feeds which has space, Steve Simon present individually with feeds which has both present.

Use should instead of must. Also you have to set minimum_should_match to 1 which means that only one should clause is needed for matching a document.

{
  "query": {
    "bool": {
      "should": [
        {
          "term": {
            "technology": "Space"
          }
        },
        {
          "term": {
            "Person": "Steve Simon"
          }
        }
      ],
      "minimum_should_match": 1
    }
  }
}
