如何实现类JSONata的JSON对象搜索建议功能？

示例数据源 #

const sourceData = {
      address: {
        city: "S Amsterdam",
        country: "Netherlands",
        line1: "Bijlmerplein 94",
        line2: "Amsterdamse Poort",
        postal_code: "1102 DA",
        state: "Noord Holland",
        newDeepTest: {
          deepTest: "deepTest Value"
        }
      },
      created: 1405637071,
      currency: "usd",
      description: "someone@example.com for Coderwall",
      email: "someone@example.com",
      name: "John Smith",
      phone: "0123456789"
    };

搜索规则及预期输出 #

• 输入"add"时，生成address节点下的所有完整子路径：address.city、address.country、address.line1、address.line2、address.postal_code、address.state、address.newDeepTest、address.newDeepTest.deepTest
• 输入"cit"时，生成带前缀的匹配结果："...city"（因city为非顶层子节点，前缀用...）
• 输入"new"时，生成匹配节点及其子路径，且前缀为...："...newDeepTest"、"...newDeepTest.deepTest"

开发诉求 #

当前该功能处于开发阶段，需要技术实现上的帮助。
