使用Google Books API进行更广泛的搜索

Question

我正在使用Google Books API创建一个非常基本的图书搜索应用。我已完成所有工作以提取并显示JSON解析的信息，但是，如果键入“举重”之类的内容，则不会返回很多结果。看起来它只是在搜索标题。下面是我提取信息的代码。有谁知道要搜索关键字的摘要或列表或返回更多结果需要做些什么？当我运行搜索时，查询看起来像这样的“ https://www.googleapis.com/books/v1/volumes?q=video+game+development&maxResults=25”

任何帮助将不胜感激。谢谢！

List<Book> books = new ArrayList<>();

    try {
        JSONObject jsonBookObject = new JSONObject(bookJSON);
        JSONArray bookArray = jsonBookObject.getJSONArray("items");

        for (int i = 0; i < bookArray.length(); i++) {
            JSONObject currentBook = bookArray.getJSONObject(i);
            JSONObject volumeInfo = currentBook.getJSONObject("volumeInfo");
            String title = volumeInfo.getString("title");
            String authors = volumeInfo.getString("authors");
            String date = volumeInfo.getString("publishedDate");
            String url = volumeInfo.getString("infoLink");

            books.add(new Book(title, authors, date, url));

            Log.v(LOG_TAG, "JSON data successfully parsed");
        }
    } catch (JSONException e) {
        // If an error is thrown when executing any of the above statements in the "try" block,
        // catch the exception here, so the app doesn't crash. Print a log message
        // with the message from the exception.
        Log.e(LOG_TAG, "Problem parsing the earthquake JSON results", e);

    }

    return books;
}
