Is twitter search down? please somebody check

I can't search multiple users, for example @jason1 OR @jason3 OR @oliver etc, twitter doesn't show me all of those account's posts, only shows me one of them, is it a new twitter update or is twitter down?

Update: Thank God it wasn't a twittter update. this twitter downs are gonna give me heart attack cuz i make money from twitter and i thought that i lost my job. it's now going back to normal. i can't describe how panincked i was until a few minutes ago. these sudden twitter downs are gonna give me a heart attack one day

Twitter is up for me.

Don't worry, if you are a normal user twitter will not limit you

Can you write what you do in a private message?

I can advise you.
