Question on offilne search

[jj10133]

• I'm currently offline P2P maps, that automatically fetches the required tiles only based on z,x,y using Hypercore and Hyperswarm. I have been able to manage to serve the protomaps in small chunk of hypercore to users.
• This made me think how about an offline map with search, curiosity brought me here tbh
• How's OSM handling the data? Where is it getting from? How are they parsing this to have search engine locally
