查无此亼
[chá wú cĭ jí]
It's more likely to say '查无此人', meaning 'there is no such person here to be found according to records'. This could hint that this name is related to an untraceable story, person, or memory. It expresses the feeling of searching but failing to find someone significant, and a kind of loss that comes from not finding what (or who) was sought after.
