The universal Search box allows you to enter a name (either first or last, but not both) and it will search your entire Qsuite account for matches in Profiles, DonateQ, EventQ, and CustomQ.  In addition to name, you can search by Unique ID.  The results are limited to the most recent transactions that match the criteria.  If you need a larger date range or have more specific information to look for, you can use the more robust search under Transactions or the individual Product tabs.
