Boost solr results based on a field value - solr

Question

I am new to solr and trying to fetch results from it. I want results which exactly matches my phrase ex: "test test1 test2" and any document which has any of these keywords, so kind of union of exact match and partial matches.
I am pretty much achieving it using dismax. Now i want the results to be sorted/boosted on the basis of some field value eg: cat:A, then cat:B then cat:C also I want this sorting to be applied first on exactly matched result then partial matched results.
Indexed data is:
[
{
"id": "001",
"name": "test test1 test2 Z",
"price": 12.9,
"cat": "A"
},
{
"id": "002",
"name": "test test1 test2 X",
"price": 91.5,
"cat": "B"
},
{
"id": "003",
"name": "test test1 test2 R",
"price": 45.5,
"cat": "C"
},
{
"id": "004",
"name": "test test1 test2 C",
"price": 78.67,
"cat": "B"
},
{
"id": "005",
"name": "data",
"price": 91.5,
"cat": "A"
},
{
"id": "008",
"name": "test test1 test2 D",
"price": 45.09,
"cat": "A"
},
{
"id": "009",
"name": "test test1 test2 B",
"price": 34.09,
"cat": "B"
},
{
"id": "010",
"name": "test test1 test2 A",
"price": 39.19,
"cat": "C"
},
{
"id": "011",
"name": "test this data",
"price": 89.19,
"cat": "A"
},
{
"id": "012",
"name": "this is my data",
"price": 89.19,
"cat": "C"
},
{
"id": "013",
"name": "test1 is this data title",
"price": 89.19,
"cat": "A"
}
]
Please help.Thanks in advance.
