I want to convert this query:

GET demo-index/_search
{
 "fields": [
 "*"
 ]
}

into something like this:

GET demo-index/_search?fields=*

is it possible to do fields queries in this way or a way similar to it without using a json body for the request?

You can try with filter_path :

If we've have the next return:

{
  "took" : 3,
  "timed_out" : false,
  "_shards" : {
    "total" : 3,
    "successful" : 3,
    "skipped" : 0,
    "failed" : 0
  },
  "hits" : {
    "total" : {
      "value" : 10000,
      "relation" : "gte"
    },
    "max_score" : 1.0,
    "hits" : [
      {
        "_index" : "demo-index",
        "_type" : "_doc",
        "_id" : "32223223d3e23dd23d2x23",
        "_score" : 1.0,
        "_source" : {
          "username" : "Mike",
          "date" : "2022-04-04"
        }
      }
    ]
  }
}

And we would like to return all fields,we should write the path as follows:

GET demo-index/_search?filter_path=hits.hits._source.*

If we would like the specifics fields like "username", we should write the path as follows

GET demo-index/_search?filter_path=hits.hits._source.username
