Text Search Inpuit Field should have more than 1 input line

Currently our UI text search has only one line. If you enter e.g. 

{
"query": { "match_none": {} },
"knn": [
  { "field": "colorvect_l2",  "vector": [0, 0, 128],"k": 3 }
],
"fields": ["color"]

}

then it's hard to have an overview about the input query
