How to make search query more flexible?

[abhijith_chandran (Tiations)]

Hi,
I am currently using this elasticsearch DSL query:

{
    "_source": [
        "title",
        "bench",
        "id_",
        "court",
        "date"
    ],
    "size": 15,
    "from": 0,
    "query": {
        "bool": {
            "must": {
                "multi_match": {
                    "query": "i r coelho",
                    "fields": [
                        "title",
                        "content"
                    ]
                }
            },
            "filter": [],
            "should": {
                "multi_match": {
                    "query": "i r coelho",
                    "fields": [
                        "title.standard^16",
                        "content.standard"
                    ]
                }
            }
        }
    },
    "highlight": {
        "pre_tags": [
            "<tag1>"
        ],
        "post_tags": [
            "</tag1>"
        ],
        "fields": {
            "content": {}
        }
    }
}

Here's what's happening. If I search for I.r coelho it returns the correct results. But, if I search for I R coelho (without the period) then it returns a different result. How do I prevent this from happening? I want the search to behave the same even if there are extra periods, spaces, commas etc.
