The https://bugzilla.redhat.com/query.cgi?format=advanced[advanced Bugzilla query form] looks dauntingly complex.
While it is complex and powerful, you can safely ignore most of the form.
Any part of the form that is left blank does not limit the search.
Each part that is filled in cuts the list of bugs down to only those that match the criteria you set.
The Status field is set by default to find NEW, ASSIGNED, NEEDINFO, and MODIFIED bugs—the unfixed bugs (or in the case of MODIFIED the recently fixed bugs).
In the product field, you should always use "Fedora", "Fedora EPEL", or "Fedora Container Images".
In the component field, select the source package that contains the defect.
If you enter more than one word and they are not a phrase, change the type of matching for the Summary field from *contains the string* to *contains all of the words/strings* or *contains any of the words/strings*, as appropriate.
Fedora generally doesn't make use of keywords in Bugzilla, so you won't usually need to use this.
Keywords are specific tags, not arbitrary words.
If you try to search for keywords that are not on the list, it won't work.
