Sort in Java API client

[vishalop0993 (Vishal Yadav)]

Hi Experts,

I am using new java API client to connect with Elasticsearch. My requirement is to search documents in sorted order of given parameters.

I have written the below code to search and sort by "customer".

        SortOptions sort = new SortOptions.Builder().field(f -> f.field("customer").order(SortOrder.Asc)).build();
        List<SortOptions> list = new ArrayList<SortOptions>();
        list.add(sort);

        SearchResponse<Order> response = elasticsearchClient.search(b -> b.index("order").size(100).sort(list)
                .query(q -> q.bool(bq -> bq
                        .filter(fb -> fb.range(r -> r.field("orderTime").
                                        gte(JsonData.of(timeStamp("01-01-2022-01-01-01")))
                                        .lte(JsonData.of(timeStamp("01-01-2022-01-01-10")))
                                )
                        )
                        .must(query)
                )), Order.class);

I am getting below Exception.'

Exception in thread "main" co.elastic.clients.elasticsearch._types.ElasticsearchException: [es/search] failed: [search_phase_execution_exception] all shards failed
	at co.elastic.clients.transport.rest_client.RestClientTransport.getHighLevelResponse(RestClientTransport.java:281)

	at model.OrderDAO.main(OrderDAO.java:45)

Same code work if I remove .sort() method.
Please let me know what is wrong with the parameter being passed in .sort() method and help me with the correct syntax for sorting.
