I'm using Elasticsearch in my .NET app and i construct a query like this:

```auto
POST xxx/_search?typed_keys=true
{
  "query": {
    "bool": {
      "must": [
        {
          "query_string": {
            "fields": [
              "FirstName",
              "LastName"
            ],
                "query": "/محمد(.*?)/ AND /محمد(ی|ي|ئ)(.*?)/"
          }
        }
      ]
    }
  },
  "size": 30,
  "sort": [
    {
      "_score": {
        "order": "desc"
      }
    }
  ]
}

```

it seems elastic can not give the correct data with this format that I'm making  
now i want to know what is the problem with this part of a query:  
"query": "/محمد(._?)/ AND /محمد(ی|ي|ئ)(._?)/"

for brief elastic will return me data but not really relevant to what I'm searching for
