PUT test/doc/3

}
PUT test/doc/4
{
  "text": """Sports Report:
Cricket - The Adelaide Strikers have blasted their way back to the top of the Big Bash ladder, after beating the Melbourne Stars."""
}

And the query is

GET test/_search
{
  "query": {
    "match_phrase": {
      "text": "th wa"
    }
  }
}

Result is

{
  "took": 0,
  "timed_out": false,
  "_shards": {
    "total": 5,
    "successful": 5,
    "skipped": 0,
    "failed": 0
  },
  "hits": {
    "total": 2,
    "max_score": 4.558014,
    "hits": [
      {
        "_index": "test",
        "_type": "doc",
        "_id": "4",
        "_score": 4.558014,
        "_source": {
          "text": "Sports Report:\nCricket - The Adelaide Strikers have blasted their way back to the top of the Big Bash ladder, after beating the Melbourne Stars."
        }
      },
      {
        "_index": "test",
        "_type": "doc",
        "_id": "3",
        "_score": 3.9283106,
        "_source": {
          "text": "2 #Quick Foxes lived died and resurrected their wys "
        }
      }
    ]
  }
}

of-course the second one is wrong.

becuse query was

th wa

so it should not bring anything with

wy

isn't it?
