Thank you for your additional information and yes you are right David on the substance everything is possible.
Nevertheless GhostHunter is a third party solution, even if it integrates with Ghost via APIv2 (with a dirtyfix…).
It has not been and is not developed by the Ghost Team and does not integrate the core standard.
For multi-language, this is still quite limited and especially requires adding about 15 to 20KB of additional code per language.
This kind of solution quickly becomes gargantuan.
What we thought when the tag went to “planned” is that when Ghost updated it would integrate its own search function, hence the term build-in.
And if I understand your answers correctly, it no longer seems on the agenda, yet many users want to see this basic integrated function.
But I understood with a time, some task become more important and some other less.
Anyway, thank you for your reply and your time to answer too and waiting about new updates and new functions in Ghost.
