I was wondering what adding solved, to a forum search, would provide.
If you go to the advanced search screen.
Search for keywords input slot:
add solved to what you are searching for.
Make sure to have search within:
Selected to Topic tittles only
Topics that have solved in the tittle will be listed.
Example:
Booting issues.
booting solved
Thinking about what a possible topic would have, for a topic tittle, helps to get closer to what you want.
Example:
fossapup64 solved
This brings up a list of only fossapup64 solved topics.
