当您想在多个字段中搜索时，可以使用 QueryBuilders#multiMatchQuery() 指定要匹配的所有字段：

NativeSearchQuery searchQuery = new NativeSearchQueryBuilder()
        .withQuery(multiMatchQuery("harry")
        .field("author")
        .field("blurb")
        .withPageable(new PageRequest(0, 10)
        .build();

SearchHits<Book> searchHits = elasticsearchOperations.search(query, Book.class);

return SearchHitSupport.searchPageFor(searchHits, pageable);

在这里，我们搜索“作者”和“模糊”字段以查找匹配项。
首先要定义一个“book实体：

@Document(indexName = "book")
public class Book {

    @Id
    private Long id;

    @Field(type = FieldType.Text)
    private String author;

    @Field(type = FieldType.Text)
    private String blurb;

    // getter/setter ...
}

第二件事是定义一个自定义存储库，该存储库描述您需要的方法：

interface BookCustomRepository {
    SearchPage<Book> findAllByAuthorAndBlurb(String query, Pageable pageable);
}

然后，我们改变 BookRepository 要扩展此新的自定义接口，请执行以下操作：

public interface BookRepository extends ElasticsearchRepository<Book, Long>, BookCustomRepository {}

现在，我们需要在一个名为 BookCustomRepositoryImpl （此名称必须与添加了实现的接口相同！）：

public class BookCustomRepositoryImpl implements BookCustomRepository {

        private final ElasticsearchOperations elasticsearchOperations;

        public BookCustomRepositoryImpl(ElasticsearchOperations elasticsearchOperations {
            this.elasticsearchOperations = elasticsearchOperations;
        }

        @Override
        public SearchPage<Book> findAllByAuthorAndBlurb(String firstName, Pageable pageable) {

            NativeSearchQuery searchQuery = new NativeSearchQueryBuilder()
                    .withQuery(multiMatchQuery("harry")
                            .field("author")
                            .field("blurb")
                            .withPageable(new PageRequest(0, 10))
                            .build();

            SearchHits<Book> searchHits = elasticsearchOperations.search(query, Book.class);

            return SearchHitSupport.searchPageFor(searchHits, pageable);
        }
    }
