Description
This query is being used to fetch the document for a given index (without any filter), but the problem with this query is that if in index's setting, the default field is set to something and if that field doesn't exists in that doc, it will not show up in the search result because of this right now I am unable to see any doc in one index and some docs are not visible in other indices.

Query :

{"query": {"query_string":{"query":"*"}},"size":10,"from":0,"sort":[]}

I think it should be replaced by this

{
  "query": {
    "match_all": {}
  },
  "size": 10,
  from: 0,
  sort: []
}

or by this

{
  "query": {
    "query_string": {
      "query": "*",
      "fields": ["*"]
    }
  },
  "size": 10,
  from: 0,
  sort: []
}

Steps To Reproduce
List the steps to reproduce your problem:

1. Open elasticvue
2. define default field in that index's setting
3. create a doc which dont have that default field.
4. just click on the index again to search and that doc will not be visible
