Today, the offline search feature still seems to be in early beta?
I am currently on the latest V3.65.1. I'm not sure if LM4 has a powerful offline search.
But at least this version only supports name search for the city attribute in LoMaps.
That is, we still can't search for road names etc in LoMaps. Why ?
Before sending this question, I also searched for it here, at least the following are discussed.
These question were basically 6 years ago. :)
