Phone contact couldn't be locate even though existed in phone book

[AC Question]

In my LG G6, If I search for a phone contact via "search contact", for example..."sat Adrian Peterson", typing from "sat Adrian p".. This contact will pop up.however, if type just "Adrian p".. This contact will not be found. It can only recognised until "Adrian". Anyone has this issue?
