By using Eclipse shortcut (CTRL+Shift+R)
Will show both (src) files and also (target) files.
Like that

The problem is that
Some times by mistake
I select the target file then i update my changes
After build i will NOT see the new changes !!
Thats because i update the wrong files (target)
So any idea
How to show only (src) files not (target) files by Eclipse shortcut (CTRL+Shift+R) ?
Derived entities are excluded from searching by default like that.

That include only those entities you want searched and search only within that working set.
