Description of problem:
For triage it would be useful to find bugs that contain a comment
"Triage->EasyFix" and do not (yet) depend on bug 109188.
Unfortunately none of the applicable boolean query "operators"
("is not equal to", "does not contain the string", "does not contain
regexp", "contains none of the words", "is null") allows doing this.
The closest we were able to get is "field does not contain the string
109188", which shows bugs that depend on something, but not on 109188.
Looks like we won't need this any more.
