使用PRAW 4在reddit上搜索帖子，适用于特定的subreddit，但不适用于"所有人"

Question

我在脚本应用中使用praw 4来搜索Reddit。当我在特定的subreddit中搜索时，我会得到一些结果，但是当我尝试在" All" subreddit中搜索时，我会得到零结果。代码：

all = reddit.subreddit("all")
for i in all.search("yellow car", limit=5):
    print i.title
cars = reddit.subreddit("cars")
for i in cars.search("yellow car", limit=5):
    print i.title

控制台日志：

DEBUG:prawcore:Fetching: GET https://oauth.reddit.com/r/all/search/
DEBUG:prawcore:Headers: {'Authorization': 'bearer tokenremoved'}
DEBUG:prawcore:Data: None
DEBUG:prawcore:Params: {'sort': 'relevance', 'raw_json': 1, 'syntax': 'cloudsearch', 'q': 'yellow car', 'limit': 5, 't': 'all', 'restrict_sr': True}

Why do most American cars have yellow in their headlights, while foreign equivalents often don't?
The M5 is a great family car!
You can have 2 cars, your daily driver and something else.  You already have your daily driver and 100k (USD) to spend.  What do you buy?

I bought my first car today r/cars!

我挖出了"所有"搜索请求的JSON响应：

{u'kind': u'Listing', u'data': {u'facets': {}, u'modhash': None, u'children': [], u'after': None, u'before': None}}

没有错误，只有空结果。

有人知道为什么搜索"全部"不会返回结果，或者下一步调试此事的下一步是什么？谢谢！

此搜索问题是Praw 4.0.0中的错误。您应该能够像安装最新开发版本的Praw4一样搜索。您可以通过：

安装该版本
