I’ve generally had pretty good luck with Spotlight on iOS, but
I’ve long noticed that results are delayed or nonexistent after
not using it for a little while, particularly if I haven’t
rebooted my phone recently. I thought I was losing my head a
little bit, until I found a tip on Twitter from Anand Iyer :
Settings > General > Spotlight Search > toggle Slack off
A week or so ago I ran into this, where Spotlight was running so slowly on my iPhone that it was unusable. Restarting my phone fixed the problem, but I’ll bet it was this Slack problem.
Update: Sounds like there might be widespread problems with Spotlight indexing on iOS 10, because a bunch of readers have written to say they have the same problem but don’t even have Slack installed.
Update 2: Several readers are saying this was a bug in iOS 10.3.1 but has been fixed in last week’s 10.3.2 update.
