Players
Use the p: parameter to list one or more players.
p:[playername]
Supports multiple (comma separated)!
Searches for activities caused by a player.
p:viveleroi will query activities in which viveleroi was the cause of the action.
Prior to Prism 4.3 this parameter also included a search for players affected by an action (player-death). To find that data now, use
pa:<player>Negation
As of Prism 4.4, this parameter allows negation. Negating an action will exclude results. It is important to note that unlike Prism 3, the syntax has the exclamation point before the colon. You cannot use a negated parameter with its normal equivalent.
Example: /pr l p!:viveleroi (Queries all players except "viveleroi")
