path invalid on windows

[jgranduel]

Hi,

thanks for this useful plugin. I'm experimenting on windows and the provided link on search results are incorrect (backslash "" escaped as '%5c' ) instead of URL path "/").

Found 4 results for test

1. blog\a.md
   localhost:2015/blog\a.md
   # <mark>test</mark> ...

This leads to error 500

[ERROR 500 /blog\a.md] http: invalid character in file path

Best regards
