Hello, after trying to upgrade to the latest version 5.4.4 it seems that sorting by inner fields is no longer working at all. This change of behavior is caused by the adjustments made in #3074.

Until now we had the following part in a separate mapping.json with no annotations at all on the name property in our User class:

{
  "user": {
    "aliases": {},
    "mappings": {
      "properties": {
        [..]
        "name": {
          "type": "text",
          "fields": {
            "raw": {
              "type": "keyword"
            }
          },
          "analyzer": "autocomplete",
          "search_analyzer": "standard"
        },
       [..]

The inner field name.raw is used for sorting purposes only, like in repository.findAll(Sort.by("name.raw").
Now the added manipulation of sort parameters added in MappingElasticsearchConverter.updatePropertiesInFieldsSortAndSourceFilter removes the .raw part from the sort parameter, which causes the whole query to fail as text fields are not optimised for sorting and therefore the operation is disabled by default.

I already tried moving the field information from the mapping.json directly to the class like the following, which created the correct mapping during index recreation, but the sort manipulation is still happening as if the model is not aware of its own inner field:

@MultiField(
      mainField = @Field(type = FieldType.Text, analyzer = "autocomplete", searchAnalyzer = "standard"),
      otherFields = @InnerField(suffix = "raw", type = FieldType.Keyword))
String name;

Am I missing something or is there no way to sort by name.raw now in the latest version?
