Field Collection モジュールに代わるものを見つけたいと思っています。問題は、フィールド コレクションのサブ フィールドを検索する (検索 API + ビューを使用している) ことです。
例として、次のフィールドを持つフィールド コレクション「フィールド」があるResearch Paperとします。
- 研究のタイトル
- PDF ドキュメント。
コンテンツ タイプとしてResearch Papersを追加したページに、いくつでも追加できます。Research Paper
以下は、たとえば、私が追加した典型的な研究論文です。
- 「植物学」、「なんとか何とかの持続可能な供給源を見つける.pdf」
- 「経済学」「客単価と気象条件の相関に関する研究.pdf」
- 「数学」、「Rational numbers.pdf 内の Pi シリーズの推定」
ここで問題が発生します。ビューで Search API を介して検索ページを作成し、「何とか何とかの持続可能なソース」を検索した場合、どうすれば「植物学」の「研究論文」エントリへのリンクを取得できますか。 blah blah.pdf の持続可能なソース"?
ビューを使用して「全文検索（公開）」で検索しています。
念のため、ビューを次に示します。
