how to filter data by multiple keywords

AAA or BBB or CCC, AAA|BBB|CCC
url_contains[], text_contains[], strip_if_url[], strip_if_text[]

PS: i have the source code, is it possible?

We’ll try to be clearer about this in a future update. You have to repeat the parameter with the brackets in the query string:

For example:

...&strip_if_text[]=keyword1&strip_if_text[]=keyword2&strip_if_text[]=keyword3...
