Possible bug on baloo

[Walter Valenti <waltervalenti@yahoo.it>]

Package: baloo4
Version: 4:4.14.1-1


Testing (jessie) i386.

If a text file doesn't have extension,
for example is called symply "NOTE",
the content of this file is not indexed, and 

is not present in "documents".

Is a bug or a design choise?

Thanks
Walter
