Querying the database is performed by the M-x query-pr command. The command prompts for the query expression, Query expressions, and displays a buffer with the list of the matching Problem Reports.
The list of the Problem Reports is displayed in the summary query format, Formatting query-pr output. Currently, the display format cannot be changed and it must output each Problem Report's number in the first column.
The Problem Report list buffer is put in the view mode, Misc File Ops (GNU Emacs). You can use most of the standard view mode commands in it. Additionally, the following special commands are available:
gnats-query-view-pr), Emacs viewing.
gnats-query-edit-pr), Emacs editing.
gnats-query-reread). The last performed query is executed again and the buffer is filled with the new results.
send-pr), Emacs submitting.
gnats-change-database), Emacs and databases.
If the value of the variable gnats-query-reverse-listing is
nil, the listing appears in the reversed order, i.e. with
the Problem Reports of the highest number first, in the buffer.
Similarly to other gnats Emacs modes, there is a hook available for the Problem Report list.
