Description of problem:
When searching for an errata and knowing its id (say RHSA-2017:1382) or CVE (here CVE-2017-7502), one has to use filter

id = RHSA-2017:1382
or
cve = CVE-2017-7502

It would be user more-friendly if one can search by providing just the id or CVE, i.e.:

RHSA-2017:1382
or
CVE-2017-7502

(This does not work atm)

Version-Release number of selected component (if applicable):
