Why does search autosuggestion work differently in the Mac app than the iOS app?

[arose10 42]

As an example, let's say I have a tag "2016 Conferences".

In the iOS app, I can type either "2016" or "Conferences", and the tag will come up in the autosuggestions.

In the Mac app, it seems I have to type the tag precisely correct letter by letter, from the start, in order for it to come up in the autosuggestions.  So typing "Conferences" doesn't trigger the tag.

Do other folks observe this, as well?  Is there any remedy to it, to make it more like the iOS app?  It makes searching a lot more frustrating.
