Elastic search- search exact matching string using query UI

问题

Here is my JSON .

{
    "id":100,
    "name":"xxx",       
    "hobbies":["cricket","footbal","singing & dancing"]

}

I need to filter "singing & dancing" string from "others". Executed below query.

http://localhost:9200/employeed/data/_search?q={"query":{"query_string":{"query" : "hobbies:Singing & dancing"}}}   

I am getting below exception.

"type": "illegal_argument_exception",
  "reason": "request [employee/data/_search] contains unrecognized parameter: [ Singing\"}}}]"  

Any help?

You're attempting to send a DSL query in a URI. The two don't mix, see here: https://www.elastic.co/guide/en/elasticsearch/reference/6.2/search-search.html

The search API allows you to execute a search query and get back search hits that match the query. The query can either be provided using a simple query string as a parameter, or using a request body.

You can either use the DSL and send it in your request body, or change your URL to just include the hobbies query_string you want to use. Like this:

http://localhost:9200/employeed/data/_search?q=hobbies%3A%5C%22Singing%20%26%20dancing%5C%22

The query_string portion is also URL encoded. I've also added quotes around your search value, otherwise it will OR them together. The unencoded version:

hobbies:\"Singing & dancing\"
