如何在elasticsearch 8.8.0中编写范围查询

  • 772

我在Spring Boot示例中为在Docker上运行的弹性搜索编写范围查询时遇到问题。

我尝试编写RangeQuery但无法实现它elasticsearchClient.search.

我怎样才能做到这一点？

这是下面显示的代码片段

public List<Item> searchItemsByPriceRange(double minPrice, double maxPrice) throws IOException {
        RangeQuery rangeQuery = new RangeQuery.Builder()
                .field("price")  // Specify the field name here
                .gte(JsonData.of(minPrice))   // Greater than or equal to minPrice
                 .lte(JsonData.of(maxPrice))   // Less than or equal to maxPrice
                .build();

        log.info("Elasticsearch query: {}", rangeQuery.toString());

        SearchResponse<Item> response = elasticsearchClient.search(q ->
                q.index("itemindex").query(rangeQuery), Item.class);

        log.info("Elasticsearch response: {}", response.toString());

        return extractItemsFromResponse(response);
}


private List<Item> extractItemsFromResponse(SearchResponse<Item> response) {
    return response
            .hits()
            .hits()
            .stream()
            .map(Hit::source)
            .collect(Collectors.toList());
}

这是问题部分

SearchResponse<Item> response = elasticsearchClient.search(q ->
                q.index("itemindex").query(rangeQuery), Item.class);

Cannot resolve method 'query(RangeQuery)'
java

    Query.Builder您需要在方法中使用 a query()，在此您可以设置rangeQuery

    SearchResponse<Item> response = elasticsearchClient.search(q -> q
  .index("itemindex")
  .query(queryBuilder -> queryBuilder.range(rangeQuery))
  ), Item.class);
