我正在尝试使用resthighlevelclient从elasticsearch进行搜索，如下所示：

RequestOptions.Builder builder = RequestOptions.DEFAULT.toBuilder()
builder.setHttpAsyncResponseConsumerFactory(new HttpAsyncResponseConsumerFactory
        .HeapBufferedResponseConsumerFactory(BUFFER_LIMIT))
SearchResponse searchResponse = client.search(searchRequest, builder.build())
return searchResponse

但对于某些搜索，我不断遇到这种过早的内容长度结束错误消息，我不知道为什么：

我已经研究过其他“以内容长度分隔的消息体过早结束”的问题，但似乎无法解决这个问题，因为这个问题直接嵌入到elasticsearch中。
为什么会这样？什么会导致它过早结束？有什么办法？
