I discovered the difference of the results of searching from Twitter website and REST API.
Urls are excluded from searching targets in Twitter website.
For example, I search “b.hatena.ne.jp” from Twitter website.
Then, the result is this screenshot.
But, the searching from REST API matches to the all texts of tweet, twitter cards and urls like https://t.co/xY2KCpnDD7 or https://t.co/Ux3BJoJKGL etc.
This difference seems to be occurring from 2016/07/02.
Is this a bug?
