Most of the time, when I open up the app and immediately start a search from the home screen (searching all vaults by default), the app returns no result.
Now if I select the vault I know the item is in, I start getting results immediately.
I sometimes get results searching all vaults, but never when I haven't used the app in a while and I just launch it. I'm wondering at this point whether it's a "delay" thing, where the app needs time to reindex the database before it really returns any result, but I thought it was worth reporting.
