Logical OR filter for one specific column

Hi,

I was looking for a solution to implement a logical OR filter for one specific column. So if there is a column NAME then I would like to have a searchbox where I can enter different names and all rows that match one of the entered names will stay visible. I think this is an easy thing to do but blame me... I did´n find the easy solution yet :-(. Can somebody point me to the right information on how to achive this?

Maybe this is also possible to realize with the main search box. But this should also stay able to filter the other columns too (but one spec. with OR).

Thanks in advance
