spring-data-elasticsearch:4.4.10 IndicesBoost error

[freedally]

spring-data-elasticsearch:4.4.10

    List<IndexBoost> indexBoosts = new ArrayList<>();
    indexBoosts.add(new IndexBoost(IndexConst.INDEX_NAME_1, 2));
    indexBoosts.add(new IndexBoost(IndexConst.INDEX_NAME_2, 1));


    Pageable pageable = PageRequest.of(0, 10);

    NativeQuery nativeQuery = NativeQuery.builder()
            .withIndicesBoost(indexBoosts)
            .withQuery(query)
            .withPageable(pageable).build();

    SearchHits<EntityAsMap> searchHits = elasticsearchTemplate.search(nativeQuery, EntityAsMap.class, IndexCoordinates.of(IndexConst.INDEX_NAME_1, IndexConst.INDEX_NAME_2));

Received exception

Caused by: co.elastic.clients.elasticsearch._types.ElasticsearchException: [es/search] failed: [parsing_exception] Expected [END_OBJECT] in [indices_boost] but found [FIELD_NAME]

Is my method incorrect?

There seems to be an error here：org.springframework.data.elasticsearch.client.elc.RequestConverter

// line 1206
if (!isEmpty(query.getIndicesBoost())) {
    Map<String, Double> boosts = new LinkedHashMap<>();
    query.getIndicesBoost().forEach(indexBoost -> {
        boosts.put(indexBoost.getIndexName(), (double) indexBoost.getBoost());
    });
    // noinspection unchecked
    builder.indicesBoost(boosts);
}

You are using the new client, what version is the server? If it is an Elasticsearch 8 server, do you set the compatibility headers?

4.4.x is out of maintenance now, can you try this with the current version (5.1)

[freedally]

elasticsearch version：7.17.8

I upgraded my dependencies：
spring-boot-starter-data-elasticsearch：3.1.1
spring-data-elasticsearch：5.1.1

I got the same result.
I set boosts to an array during debugging and got the correct result.

if (!isEmpty(query.getIndicesBoost())) {
  Map<String, Double> boosts = new LinkedHashMap<>();
  query.getIndicesBoost()
	  .forEach(indexBoost -> boosts.put(indexBoost.getIndexName(), (double) indexBoost.getBoost()));
  // noinspection unchecked
  builder.indicesBoost(boosts);
}

I set boosts to an array during debugging and got the correct result.

what do you mean with that, where do you change?

[freedally]

I got the correct result after making the modifications like this.
org.springframework.data.elasticsearch.client.elc.RequestConverter

  // line 1414
  if (!isEmpty(query.getIndicesBoost())) {
	  List<Map<String, Double>> boosts = query.getIndicesBoost().stream()
			  .map(indexBoost -> Map.of(indexBoost.getIndexName(), (double) indexBoost.getBoost()))
			  .collect(Collectors.toList());
  
	  // noinspection unchecked
	  builder.indicesBoost(boosts);
  }
