You might want Recoll[1]. Similar if less powerful capabilities, cross-platform, open source, has Windows and macOS installers.
Still an overly complex FOSS user interface for a tech-unsavvy target with lots of digging around to configure it (OCR setup, for instance[2]), but at least you don't need to know what Docker is to install it.
