Since: vs since_id


s the “since:” syntax and the “since_id” query string parameter the same thing? I’m trying to perform searches for a hashtag from a particular time onwards. I’ve read that you can use the since_id to return results greater than the value of it. But what If you didn’t have a value in the first place?

Even If…can’t you STILL use the “since:” syntax as well? How does it affect the search results?
