Hi @julianadefreitasdias
Thanks for reaching out and apologies for the delay in response as the team was out on holiday. 
Great question, you’re touching on two related but slightly different things: Boolean operators and regex in GA4.
Boolean operators
Supermetrics supports both AND and OR.
For your case (SOURCE OR SELL OR LIKE):
Here’s our guide on filters →
Regex
You can also do this with one filter using regex. The pipe symbol |
acts like OR:
SOURCE|SELL|LIKE
Just note GA4 has a 256-character regex limit. Supermetrics can handle more, but using multiple OR filters is safer for long queries.
If you ever need help building more complex filters, our support team’s always here.
