Spotlight Custom Shortcodes?

Hello,
I am wondering if it is possible to define custom shortcodes for Sportlight? Well, I am sure in the basic settings it is not possible but maybe a small program or script which makes it possible or adding some .plist file?

I mean with shortcodes that by typing in spotlight "os" and hit enter it instantly opens safari without I have to wait that spotlight "finds" safari and then I can hit enter. sometimes I type something, it already shows the app i am looking for, but obviously it was the result for the first letters I typed and by the time I hit enter, he already searched for all the text I entered and it opens a different app.
By having these shortcodes I could define in a List "txt" => "open TextEdit", "txtw" => "open TextWrangler" and so on. It would be faster and those mistakes as decribed above would not happen.

Do you know what I mean and does someone have an idea how to find a solution for that?
That would be great!
Thank you very much.

PS: I use OS X Yosemite

 

I already found one way, although it is not spotlight, but quite similiar:
Using the terminal. I just add in .bash_profile aliases to the apps or files I want with the command "open" in front...
that works, but nicer of course would be something right inside Spotlight...
