I am using Elasticsearch 7.4 and java client api. I want to use context suggester with search api given in this document [Suggesters | Elasticsearch Guide [8.6] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-suggesters.html#context-suggester)  
can any one give me any sample documents which explains how to do in java api service

I am querying like this

```auto
POST ***_autosuggest/_search?pretty
{
  "suggest": {
    "place_suggestion": {
      "prefix": "tim",
      "completion": {
        "field": "suggest",
        "size": 10,
        "contexts": {
          "genre": [" **-faculty", "** -companies"]
        }
      }
    }
  }
}

```

and my mapping is

```auto
{
  "**_autosuggest": {
    "aliases": {},
    "mappings": {
      "properties": {
        "dictionary": {
          "type": "keyword",

            {

              "type": "CATEGORY"
            }
          ]
        },
        "suggestion": {

            }
          }
        },
        "title": {
          "type": "keyword",

        }
      }
    },

                "_english_"
              ]
            }
          },

              ],
              "type": "custom",
              "tokenizer": "standard"
            }
          }
        },
        "number_of_replicas": "0",

        }
      }
    }
  }
}

Hi @mangeshs

This example is using Java High level. I hope it helps you get started.

```auto
 public static void main(String[] args) throws IOException {

    var suggestBuilder = new SuggestBuilder();
    var searchSourceBuilder = new SearchSourceBuilder();

    suggestBuilder.addSuggestion("place_suggestion", SuggestBuilders.completionSuggestion("suggest")
        .skipDuplicates(true)
        .contexts(getContext())
        .prefix("tim"));

    searchSourceBuilder.suggest(suggestBuilder);

    var searchRequest = new SearchRequest();
    searchRequest.source(searchSourceBuilder);
    SearchResponse result = getClient().search(searchRequest, RequestOptions.DEFAULT);
  }

  public static Map<String, List<? extends ToXContent>> getContext() {
    List<CategoryQueryContext> ctx = new ArrayList<>();
    ctx.add(CategoryQueryContext.builder().setCategory("**-faculty").build());
    ctx.add(CategoryQueryContext.builder().setCategory("**-companies").build());
    return Collections.singletonMap("genre", ctx);
  }

```
