"match-boolean-query doesn't return the "exact match word" of the query

[paris1 (ParisaMoghaddas)]

I'm using "match-Boolean-prefix query but I can't get the exact match of the query.I can't use prefix queries because I also need "not exact match" results and I also need the fuzziness and word completion.I get every thing I need by match-boo-prefix query(the fuzziness not work that good though) but my problem is when I'm looking for exact match like "apple" it shows everything that includes "apple" I need the exact match gets higher ranking than others.

    ],
    "size": 20
}

the result I'm getting with this query is :

"_score": 88.10016,
                "_source": {
                    "status": "A",
                    "name": "Milkhsake, Chocolate",
_score": 86.66473,
                "_source": {
                    "status": "A",
                    "name": "Milky Milk",
score": 86.64781,
                "_source": {
                    "status": "A",
                    "name": "Milkis",
........

The exact result of "milk" goes down the list.

Is there any suggestion how can I fix this issue?
