When we set the search criteria on the basis of assignee. We can select only one assignee. If we want to search issues which are assigned to more than one person, we cannot do that. One option is to select the option "Specify Group". But a group might have more than 2 members. So i want something like "Specify Users" where i can choose more than one assignee in a comma separated format. Like adding users to project roles. This would help a lot.
