I often use 'File Search' in Eclipse CDT and use 'Enclosing project'. Results include matches within compilation folders that I am not interested about.
I can create a 'Working set' but I've got around 25 projects and changing the working set all the time doesn't make me work faster.
Is there a way to continue using 'Enclosing project' but filter out any file that is not coming form a repository / shared in the Team? I normally use SVN but I'd rather something that works for any file that has been shared in a repo.
Set the compilation folders as derived: right-click and choose Properties: Resource and check the checkbox Derived.
Derived files are by default excluded from the File Search (in the File Search dialog is a checkbox that can be checked if derived files should also be searched).
