How to take word order into account in match_phrase query

[mehdi89 (Mehedi Hasan)]

Suppose that my index have two documents:

1. "get my money"
2. "my money get here"

When I do a regular match query for "get my money", both documents match correctly but they get equal scores. However, I want the order of words to be significant during scoring. In other words, I want "get my money" to have a higher score.

So I tried putting my match query inside the must clause of a bool query and included a match_phrase (with the same query string). This seems to score hits correctly until I do a search with "how do I get my money". In that case, match_phrase query doesn't seem to match, and the hits are returned with equal scores again.

How can I construct my index/query so that it takes word order into account but does not require all searched words to exist in document?

Index mapping with test data

PUT test-index
{
  "mappings": {
      "properties" : {
        "keyword" : {
          "type" : "text",
          "similarity": "boolean"
        }
      }
    }
}

POST test-index/_doc/
{
    "keyword" : "get my money"
}
POST test-index/_doc/
{
    "keyword" : "my money get here"
}

Query "How do I get my money" - Doesn't work as needed

GET /test-index/_search
{
  "query": {
    "bool": {
      "must": [
        {
          "match": {
            "keyword": "how do i get my money"
          }
        }
      ],
      "should": [
        {
          "match_phrase": {
            "keyword": {
              "query": "how do i get my money"
            }
          }
        }
      ]
    }
  }
}

Results (Both documents scored same)

{
  "took" : 2,
  "timed_out" : false,
  "_shards" : {
    "total" : 1,
    "successful" : 1,
    "skipped" : 0,
    "failed" : 0
  },
  "hits" : {
    "total" : {
      "value" : 2,
      "relation" : "eq"
    },
    "max_score" : 3.0,
    "hits" : [
      {
        "_index" : "test-index",
        "_type" : "_doc",
        "_id" : "6Xy8wXIB3NtI_ttPGBoV",
        "_score" : 3.0,
        "_source" : {
          "keyword" : "get my money"
        }
      },
      {
        "_index" : "test-index",
        "_type" : "_doc",
        "_id" : "6ny8wXIB3NtI_ttPGBpV",
        "_score" : 3.0,
        "_source" : {
          "keyword" : "my money get here"
        }
      }
    ]
  }
}
