CTA 5.32 Deep Search

Hello, when doing a deep search for “lightsword” i get a result like seen in the image. For example “beam.iprop”

What exactly does that mean ? I can not find this item neither in my database nor in the RL Marketplace. Its not a trial either. Can i just use it and first of all where is this item located when not in the marketplace like selected (right) ?

This tut does not make sense to me

(minute 2:09 -2:25) where you can use an item which hasent been purchaed yet.

Can someone explain this to me ?
