There is a way to use multiple analyzers?

Hi everyone, I'm starting my way to learn and use elasticsearch alongside the "MEN" stack. And I was wondering if there is a way to use multiple parsers, I show you the section of code that I want to use:

query = {
    "bool": {
        "must": [
            {
                "multi_match": {
                    "query": strQuery + "~",
                    "fields": ["strDescription^10", "strCategory^30", "strSubCategory^40", "strVendorPart"],
                    "minimum_should_match": "95%",
                    // This part is where I want to add another parser
                    "analyzer" : "elastic_synonym_analyzer"
                }
            }
        ],
    }
};

The index I'm working with is the following:

{
    "settings" : {
        "analysis" : {
            "analyzer" : {
                "standard_asciifolding": {
                    "tokenizer": "standard",
                    "filter": [ "my_ascii_folding" ]
                },
                "elastic_synonym_analyzer" : {
                    "tokenizer" : "standard",
                    "filter" : [
                        "my_synonym"
                    ]
                }
            },
            "filter" : {
                "my_synonym" : {
                    "type" : "synonym",
                    "synonyms" : []
                },
                "my_ascii_folding": {
                    "type": "asciifolding",
                    "preserve_original": true
                }
            }
        }
    }
}

I hope you can help me.

P.S. The version I am using of elasticsearch is 6.2.4 (I know it should increase but first I want to know how to solve this problem)

You should create new sub fields for the same existing fields which are using another analyzer.
