There are three explanations that I know of:

- They were still in the instance while you were searching them, therefore they wouldn't show up

- They have a tank of a PC and already exited and insta-queued something else before you searched them

- They crashed/were no longer online

It doesn't sound like a bot because bots will still show up if you search and there is no in game way (or out) to hide yourself. I'd honestly try to look via the lodestone first rather than rely on the in game search.
