NativeSearchQuery返回所有结果，即使在作为查询的一部分传递单个标识符时也是如此

Question

List<String> ids = List.of(id);
NativeSearchQuery query = new NativeSearchQueryBuilder()
.withSourceFilter(new FetchSourceFilterBuilder().withIncludes(section).build())
.withIds(ids)
.build();
log.trace("query {}", query.toString());
SearchHits<Foo> searchHits = operations.search(query, Foo.class, index);

上面的代码片段生成了以下查询，但不清楚为什么它会获取所有Foo，因为我已经明确提到使用withIds(ids)使用单个id

Answer 1

withIds()在另一个上下文中使用(即通过_mget按ID检索多个文档时(。

在您的情况下，您应该简单地进行一点不同的处理，即在_id字段上使用terms过滤器：

NativeSearchQuery query = new NativeSearchQueryBuilder()
.withSourceFilter(new FetchSourceFilterBuilder().withIncludes(section).build())
.withFilter(QueryBuilders.termsFilter("_id", ids))
.build();
