[surajdalvi (Suraj)]

I am storing URL in the elastic search and I making the following request to get a result for elastic search:

{
                        "query_string": {
                            "query": "*http://localhost:8000/v3/assets/dt1234/dt3335/605f068b5e124230eadea17a/my.png*",
                            "fields": ["url"],
                            "default_operator": "OR"
                        }
                    }

but elastic search giving Me the following error:

I reproduced the problem with the following script and fixed it. See:

DELETE test 
PUT test 
{
  "mappings": {
    "properties": {
      "url": {
        "type": "keyword"
      }
    }
  }
}
POST test/_doc
{
  "url": "http://localhost:8000/v3/assets/dt1234/dt3335/605f068b5e124230eadea17a/my.png"
}
GET test/_search
{
  "query": {
    "query_string": {
      "query": "*\"http://localhost:8000/v3/assets/dt1234/dt3335/605f068b5e124230eadea17a/my.png\"*"
    }
  }
}
