It is possible to give all user related arguments in a query on user related bugs

[Markus Korn]

Steps to reproduce this bug:
 1.) go to https://bugs.edge.launchpad.net/~wgrant/+bugs?advanced=1
 2.) enter "thekorn" in "Assignee", "Reporter", "commenter", "subscriber", and "Project, ... subscriber" fields
 3.) click on "search"

the resulting page is https://bugs.edge.launchpad.net/~wgrant/+bugs?field.assignee=thekorn&field.bug_reporter=thekorn&field.structural_subscriber=thekorn&field.bug_commenter=thekorn&field.subscriber=thekorn

This page shows two bugs which are unrelated to wgrant, because all user related query fields are overwritten.

I think this a fairly uncommon scenario, but it does show some a design problem in the search approach.

A "correct" way to solve this might be be to make the result an intersection of all the user-related bugs and those discovered from the specific search request. In other words, only search within the set of user-related bugs.

Perhaps a less surprising solution would be to show an error if all the user-related query fields are specified as users other than the context.

This is a more common scenario which also returns wrong results:

https://bugs.edge.launchpad.net/~thekorn/+bugs?field.assignee=allenap

This bugs are by no means related to me

[Gavin Panella (allenap)]

Yes, those results are flat out wrong.
