How does dolphin search work?

In Dolphin, the filenamesearch directory contains search results, but they are neither symlinks nor hardlinks. file, ls, and stat fail with ‘Inappropriate ioctl’. How does Dolphin generate these entries, and where are the original paths stored? Baloo is not active for me. Thanks for any hint.

You have done a search and see the results appear in a panel?

… you then go to the search box and see a URL starting “filenamesearch:…”?

That’s not a folder on your system, that’s just a set of results returned by the “filenamesearch” code. You can ask Dolphin to display various columns, the path is useful and the modified date.

Yes, I guess there is a internal “database”, which “links” displayed information and real files. This shouldn’t be complicated, but how is this database called, and can I connect to this database to retrieve and manipulate some values?
