Hi @Tim_Grose 
You are right here. The search result does not support partial word search. I’m confident this is something we will fix in the future, but I don’t have any precise update to share at the moment.
In the meantime, you could try with the results preview that support partial word search. I know this is not ideal but it might help in your search.
Just to let you know, we already have a thread on the Forum about this in the #productfeedback category: Partial word search matches - #2. If you haven’t yet, feel free to add your vote and comment: . I’ll make sure to update this thread as soon as I have an update about it.
Have a great Wednesday!
