Twitter – Why is Twitter search not finding results

twitter

I tweeted something via Twitter and then tried to search for it. The tweet is https://twitter.com/bgoodr2/status/638042917056065536 so I searched for:

Allow Intra-PDF document link navigation

and that gave nothing (URL was https://twitter.com/search?f=tweets&q=Allow%20Intra-PDF%20document%20link%20navigation&src=typd). I tried searching for:

Intra-PDF

and received some results (URL was https://twitter.com/search?q=Intra-PDF&src=typd). I then tried to include the "to:" operator:

"Intra-PDF" to:dochubapp

which gave https://twitter.com/search?f=tweets&q=%22Intra-PDF%22%20to%3Adochubapp&src=typd but my tweet did not show up there.

Is this the same situation as described in the answer to Why is my tweet not appearing, and when might it appear?

If so, then that is puzzling: I would have expected it to show me my own outbound tweets even if they aren't showing up in the feed of the recipient.
