Cause

Target name includes dashes (-)

SharePoint 2013 treats hyphens (the '-' character) as a word brake character. Here is the Microsoft development support case link:

SharePoint creates the file the first time properly. Then the file gets indexed. The indexing process seems to use a text processor to originate entries. This way the index would contain text with hyphens('-') replaced by path-separating slashes: '/'.

 

Another MSDN tech discussion confirms this:
