There doesn't appear to be a Search method for Notifications, or for selecting comments that have been marked with the new Meta Tag Such as Helpful.
--If there is such a method, how do I go about it?--* If not we should submit this as an enhancement, if not already..
*(We need a crossed out Tag BTW)
A description of how this feature might work:
1) List / Search a chronological history of my own activity (or activity by any user I guess)
2) Advanced Search Match new status tags for Questions/Comments/Article (And who applied them -- Separate Search terms maybe?)
2a) When Applied to a Specific Expert (say, myself) By Anyone
2b) When Applied to Anyone By a specific Expert (Say Myself)
2c) When Applied by Specific Person(s) to Specific person(s) (EGs follow)
2ci) Me to Expert A and/or Expert B
2cii) Me and Expert A to Expert B and/or Expert C and or Expert D
2ciii) Expert A or Expert B to Me and/or Expert C
2civ) Expert A to Me and/or Expert B
2v) Expert A and/or Expert B to Expert C and/or Expert D
3) List and Search all previous Notifications received. (Might be easier in the short term, but if we get the above this might not be needed as I was attempting to see my notifications to try to search them for the above really)
