How to use if contains within an arrayformula and multiple or conditions?

I want to replace the "=" in the following example with a text contain to match entries partially instead of entirely.

However, I cannot get this to work. I thought I could replace the (A2:A="Neckarau / Lindenhof") with a regexmatch(A2:A;"Neckarau") but I am getting a formula parse error.

Can anyone help me with this?

={"Anzahl";arrayformula(IF((A2:A="Selbstabholer")+(A2:A="Neckarau / Lindenhof")+(A2:A="Seckenheim /  Edingen")+(A2:A="Wallstadt / Oikos / Spinelli")>0;"";IF((A2:A<>"")*(I2:I="")*(I3:I="")=1;"ausblenden";IF(I2:I="";"";H2:H))))}
