I understand what you mean, and tend to agree, although I had some success with zypper se -d '/CD.*burn/'—'CD.*(burn)|(writer)' produced more results than I’d like—for your example. It also appears apt-cache search already searches descriptions by default.

Looking at results for just /CD/—amid the many poor results—it seems my earlier search missed some due to differing word usage, such as recording rather than burning, and whatnot.
