Twitter: Hash tag search query

I am trying to search twitter tweets by a given hashtag. I am trying to get the correct http query, but I have no idea which one. I've tried a few but i can't find the correct one.

I should use the http://api.twitter.com/1/... link.

I already have a search http query by a given name which works correctly

http://api.twit开发者_运维技巧ter.com/1/statuses/user_timeline.json?screen_name=prayforjapan

Now I would like to search by a given hashtag (for example #prayforjapan)

I tried using a few, but can't find the correct one as I said before. Here's one I tried:

http://api.twitter.com/1/statuses/public_timeline.json?include_entities=true&hashtag=prayforjapan"

Does anyone know which one I should use?

Thanks!

You can simply fetch http://search.twitter.com/search.json?q=%23test to get a list of tweets containing #test in JSON, where %23test is #test URL encoded.

Just for people who come this post now. This current format works

https://api.twitter.com/1.1/search/tweets.json?q=%23test&include_entities=true

I use the http://search.twitter.com/search.json?q=%23test format shown above, but in recent weeks this format has stopped working. It returns valid JSON, yes, but the return has zero tweets while a manual search of the hashtag on twitter.com shows one or more results. This happens with every hashtag I try. Has anyone else experienced this?

Edit: I've also noticed that adding a hyperlink to a tweet causes it to show up only in my feed, while it fails to show in either site search or JSON. I'm a Twitter novice; am I missing something basic here?
