如何解决如何使用超级账本结构对 couchdb 中的对象数组应用分页？

这里我第一次只想要 2 个交易而不是下一个。所以我使用了 getQueryResultWithPagination 方法但它不适用于单个对象。所以我创建了一个 CouchDB 视图。

"views": {
    "tx-view": {
      "map": "function (doc) {if(doc.transactions.length > 0) {          emit(doc.transactions); }}"
    },"tx-view-2": {
      "map": "function (doc) { if(doc.transactions.length > 0) {      doc.transactions.forEach(function (tag) {    emit(doc.user_id,tag);  });}}"
    }
  },

我可以将此视图添加到链码查询方法中并为其创建事务吗？ 我该如何解决？
