You can use the = sign in the Path column. You can couple that with a phrase search to help you further refine to what you are looking for, but you may not be able to filter entirely.
In your second example, try searching for:
project= -"project meetings"
which would filter out at least any paths that contained "project meetings"
In your first example, try searching for:
"d test path"
which would filter out "d:\test\pathAnother". Again, this won't be perfect, since it won't filter out "d:\test\path other", but it will get you closer to what you need.
If you have control over the file directory naming structure, and it's not too many files that are affected (since X1 will have to reindex once you change the path), you might consider renaming the folder or folder path to help make it more searchable with x1.
