Checklist

• I'm asking a question and not reporting a bug or requesting a feature
• I've looked through the README
• I've verified that I have updated yt-dlp to nightly or master (update instructions)
• I've searched known issues and the bugtracker for similar questions including closed ones. DO NOT post duplicates
• I've read the guidelines for opening an issue

Please make sure the question is worded well enough to be understood

def get_youtube_search(keyword, max_results=10):
ydl_opts = {
'quiet': True,
'skip_download': True,
'extract_flat': True,
'default_search': 'ytsearch',
'noplaylist': True, # 避免搜索结果返回整个播放列表
}

with YoutubeDL(ydl_opts) as ydl:
    # "ytsearch10:关键词" 将搜索与“关键词”相关的前10个视频
    search_keyword = f'ytsearch{max_results}:{keyword}'
    result = ydl.extract_info(search_keyword, download=False)
    return format_crawler_data(result)

Provide verbose output that clearly demonstrates the problem

• Run your yt-dlp command with -vU flag added (yt-dlp -vU <your command line>)
• If using API, add 'verbose': True to YoutubeDL params instead
• Copy the WHOLE output (starting with [debug] Command-line config) and insert it below

description is None

please show complete verbose output (replace 'quiet': True with 'verbose': True in your ydl opts)

The problem is that you use extract_flat. From the search playlist alone, we don't know the full description. If you always want the description, you need to let the video extract as well.

Youtube only returns partial descriptions with the search results (what you get with extract_flat). See #6717 (comment)
