Rule-based Row filter LIKE OR combined

I have a column named appt_name which includes free text.

I want to keep only the rows that include at least the words "repair" OR "service"

I use the Rule-based Row filter node and I write the following:

$appt_name$ LIKE "*repair*" OR $appt_name$ LIKE "*service*"=>TRUE

and it does not not give me what I need. What's the right expression.

Thank you.
