この関数を実行すると、次のようになります。

しかし、ブラウザのアドレスバーにある生成されたクエリを入力しても、Google の同じクエリは結果を返し、有効な結果を返します

http://ajax.googleapis.com/ajax/services/search/web?v=1.0&rsz=small&q=%22What+is+the+best+tool+to+do+plagiarism+checking

しかし、私は結果を得ることができません。誰かが私が間違っていることを助けて説明してもらえますか?

Web Search API docsで、Google は次のように述べています。

Google Web Search API は、2010 年 11 月 1 日に正式に廃止されました。Google の廃止ポリシーに従って、廃止日から 3 年以上にわたって運用されていました。運用の最終日は 2014 年 9 月 29 日でした。別の解決策を提供する可能性があるCustom Search APIを調査することをお勧めします。
