Full text search engine was not left out for performance reasons but for practical ones.
Yes, we don't want people to generate the index on their phone. Except for tiny tiny zim files, it would be too much CPU, battery and time consuming.
But we do want to add full text search to Android.
It could work today but the search index is a (large) folder so it would be a pain to setup.
As soon as we integrate both the ZIM file and the index in a single file, we'll enable full text search on the Android App.

Hope that helps,

Looking at the Kiwix app for Android, it doesn't seem to have full-text
search within articles (unless I missed it). I assume that this was left
out of the Android version for performance reasons.

Don't assume, ask Emmanuel (cc Offline-l).
If I understand correctly, you're talking of small selections of articles (hundreds or thousands). Making an index for tens of GB of text takes hours, so Kiwix doesn't always make one (on desktop, you usually download the pre-made index). But for few articles, the problem is easier (and one can also reduce compression).
In general, I have no idea what it means that "zero team starts to think about pre-loaded content": sounds a lot like reinventing Kiwix, which would be a disastrous idea. :)
