/*
This is a Example program to retrieve and display the list of the data. Press the play/reload button on the right of the upper screen, and the program is executed. The program first displayes the subjects that match the keyword completely. The program highlights the list fragments that match the keyword. The keyword is retrieved from the query following "subject=" in the URL, where the keyword must be encoded. Please create a new application by rewriting this program work. The following is the same content in Japanese.
このサンプルプログラムはデータを取得してリスト表示します。画面右上のplay又はreloadボタンを押すとプログラムが実行されます。プログラムはキーワードに完全一致するサブジェクトを最初に表示します。またプログラムはキーワードに部分一致するリスト中の部分をハイライトします。キーワードはURLの中で"subject="に続くクエリーから取得されます。ただし、キーワードはURIエンコードされている必要があります。このプログラムを書き変えて新しいアプリケーションを作成してください。
