extract two character acronyms along with accompanying term, such as 3D-printing or 4k applications

Dear Experts:

I managed to extract 2-character acronyms (number + letter), such as 3D, 4D, 4K etc. with the following search expression (wildcards checked)

<[0-9]{1}[A-Z]{1}

The search works just fine for the above expressions.


I also would like to be able to extract these kinds of acronyms along with accompanying terms (with or without hyphen) such as ...

3D animations
4D-printing
4K applications
4K-applications

How is the above search term to be extended to accomodate my requirements.

Help is much appreciated. Thank you very much in advance.

Regards, Andreas
