Search can not find C1's own created duplicate files (with the ' 1' extension - notice the space before the number))

When exporting files C1 can not find it's own exports (when 'add suffix' option was selected). The search engine can not find file names that have a space before a digit like 'myfile 1.tif' (searching for " 1").
In other words, when I just exported duplicate files and want to find them later I cannot do that using the 'search' option. This behaviour is generic, i.e. when naming a file 'myfile ps.tif' it can not be found either. When I name it 'myfile-ps.tif' search wil give a result.

In general this is annoying, but when C1 by itself creates suffixes like 'myfile 1.tif' instead of 'myfile-1.tif' by default and then can not even find the files C1 itself just created it becomes really strange. Why not create a suffix like '-1' if it can not handle ' 1'?
