help you fix your problem Add a weight to each document – the higher the number, the higher it's prioritized.
That is, sort your output strings lexically and then enumerate them. Finally, subtract their index from 2 ** 31 - 1 (the highest priority) to get suggestions in lexically ascending order.

will help you The completion suggester doesn't use traditional search at all, so you can't automatically post-filter your suggestions. You have a few options:

wish of those help In order to use completion feature, you need to dedicate one field, which will be called completion and you have to specify a special mapping for it.
For example:
code :
"mappings": {
   "article": {
     "properties": {
      "content": {
        "type": "string"
      },
     "completion_suggest": {
      "type": "completion"}
     }
   }
}
curl -XPOST localhost:9200/kodcucom/article/1 -d '{
   "content": "elasticsearch",
   "completion_suggest": {
     "input": [ "es", "elastic", "elasticsearch" ],
     "output": "ElasticSearch"
   }
}'
CompletionSuggestionBuilder skillNameSuggest  = new CompletionSuggestionBuilder("complete");
skillNameSuggest.text("es");
skillNameSuggest.field("completion_suggest");

SearchResponse searchResponse = client.prepareSearch("kodcucom")
        .setTypes("article")
        .setQuery(QueryBuilders.matchAllQuery())
        .addSuggestion(skillNameSuggest)
        .execute().actionGet();

CompletionSuggestion compSuggestion = searchResponse.getSuggest().getSuggestion("complete");

List<CompletionSuggestion.Entry> entryList = compSuggestion.getEntries();
if(entryList != null) {
    CompletionSuggestion.Entry entry = entryList.get(0);
    List<CompletionSuggestion.Entry.Option> options =entry.getOptions();
    if(options != null)  {
        CompletionSuggestion.Entry.Option option = options.get(0);
        System.out.println(option.getText().string());
    }
}

hop of those help? ElasticSearch 6.1 has introduced the skip_duplicates operator. Example usage:
code :
{
  "suggest": {
    "autocomplete": {
      "prefix": "MySearchTerm",
      "completion": {
        "field": "name",
        "skip_duplicates": true
      }
    }
  }
}

will be helpful for those in need You can set the "size" attribute in the search request.
Look at the documentation at https://www.elastic.co/guide/en/elasticsearch/reference/current/search-suggesters-completion.html
code :
POST music/_search
{
    "_source": "suggest", 
    "suggest": {
        "song-suggest" : {
            "prefix" : "nir",
            "completion" : {
                "field" : "suggest", 
                "size" : 20 
            }
        }
    }
}
