Search rules about position list and department list

Hi Team

I want to know the search rules about the position and department .

For example , in position page , i enter the name about a position in Chinese , and then click search , there are too many rows show in the list.

But the values ​​shown in the list seem to have nothing to do with the name. (The value's name, code, parent department, etc. are all unrelated to the information I entered in the search field)
