Search matches an exact public id only, such as rin#4821. You cannot search by email address or by real name — that is a deliberate privacy rule, not a missing feature: it stops anyone turning a name they already know into an account.
A cached read model, not a live count — rebuilt every few minutes, so a match you just finished may not be in it. Ties are broken by who reached the rating first: the earlier arrival ranks higher.
History holds public match summaries only — outcome, mode, rating change and when it happened. Full replay data, including anyone's hand, is restricted to authorised investigations and is never served to a player, so you cannot pull another player's cards out of this list.
