我希望找到 Field Collection 模块的替代方案。问题是我想搜索（我正在使用搜索 API + 视图）字段集合中的子字段。
例如，如果我有一个字段集合“字段”，例如Research Paper，具有以下字段：-
- 研究名称
- PDF 文档。
我可以Research Papers在我添加Research Paper内容类型的页面中添加尽可能多的内容。
例如，以下是我添加的典型研究论文：-
- “植物学”，“寻找可持续的来源 blah blah.pdf”
- 《经济学》、《顾客消费与天气状况相关性研究.pdf》
- “数学”、“在有理数中估计 Pi 级数.pdf”
现在，问题来了，如果我通过一个视图通过 Search API 创建一个搜索页面，并搜索“ blah blah 的可持续来源”，我如何获得“Botany”的“Research Paper”条目的链接，“Finding a blah blah.pdf 的可持续来源”？
我正在使用视图并通过“全文搜索（公开）”进行搜索。
这是视图，以防万一：
