Ignoring '\' in filtering paths in the 'path' column header

The value of the path textbox filters by matching the alphanumeric contents and ignores directory separator characters ('\').

So if I have indexed in X1 the following directories:
d:\test\path
d:\test\path\subdir
d:\test\path other
d:\test\pathAnother
d:\test\dir

If I enter for the path d:\test\path\, I get results from:
d:\test\path
d:\test\path\subdir
d:\test\path other
d:\test\pathAnother

Instead, what I want is the the trailing directory separator to filter the directories so I only get results from:
d:\test\path
d:\test\path\subdir

If I enter for the path d:\test\path, without the trailing directory separator, then I expect to results all the directories:
d:\test\path
d:\test\path\subdir
d:\test\path other
d:\test\pathAnother
