Is there a way to restrict the search to questions where that one answer isn't mine? That would help. :-)
It's certainly possible to search for your own posts, but it's not possible to exclude your own posts as far as I can tell:
-user:mesearches for posts that don't have the string "user:me".
user:1-67doesn't search for posts from user #1 to user #67, but searches for posts from user #167. (And I'm not sure that will help anyway since I don't think it would be possible to simultaneously exclude 69-
-Ericsonsearches for posts that don't include my last name, but since my last name is in the the metadata and not the searchable portion of posts: no joy.
And of course none of this will actually work to eliminate the questions that that I've answered already and want to ignore. In general, If I'm involved in a Q&A (or quan) the notification procedures do a good job of keeping me up-to-date with developments. But when I search, it's often to find questions I've not noticed before. So being able to eliminate questions I have already answered would be a generally useful feature for me.
