{"offset": 0, "next": 2,
 "data": [{"paperId": "204e3073870fae3d05bcbc2f6a8e263d9b72e776",
           "title": "Attention is All you Need", "year": 2017, "citationCount": 201069,

只认 limit / offset / fields / publicationDateOrYear，其它参数静默忽略、连值都不校验（实测 year=abc 照样 200）：year / venue / publicationTypes / minCitationCount / sort 都不生效。按年筛用 publicationDateOrYear；返回顺序本来就是 citationCount 降序、同引用数按入库顺序升序。
