Maybe I didn't understand something

1.If I add optional modifier to the search folders to some directory,then if I don't write the modifier when I search,FARR will not search only in folder that don't have modifiers...for example if I add 3 different files with almost the same name into 3 different sub-folders and add the main folder to FARR and add some modifier,when I search for those 3 files,FARR will not display anything,but if I add the modifier then it will display all 3 files.

I thought that adding the modifier will limit the search to only a certain folder and FARR will search everywhere if I don't(including the location on which I set modifier)

Another example:
Add program files to the search directories and add for example "programs" for modifier.
Now if I search like this "+programs FindAndRun" FARR will display the result but if I don't add +programs,FARR will not find anything.

2.Am I doing something wrong or I didn't understand how it works...I don't have any plugins and anything that I try to install,don't appear.

3.Is there is a way when I start FARR with Pause/Break to make it search in the directory that I currently am(without typing the path to it...just add some alias and to make it search only there)
