8 – How do I retrieve multiple values in a CONTAINS condition?

I’m using the JSON:API module (in core since Drupal 8.7), which works well for a Retrieve all articles with title that contains “MyKeyValue” or subtitle that contains “MyKeyValue” which, translated in JSON:API query becomes:

fields(node--article)=title,field_subtitle
filter(or-group)(group)(conjunction)=OR
filter(status)(value)=1
filter(title-filter)(condition)(path)=title
filter(title-filter)(condition)(operator)=CONTAINS
filter(title-filter)(condition)(value)=MyKeyValue
filter(title-filter)(condition)(memberOf)=or-group
filter(subtitle-filter)(condition)(path)=field_subtitle
filter(subtitle-filter)(condition)(operator)=CONTAINS
filter(subtitle-filter)(condition)(value)=MyKeyValue
filter(subtitle-filter)(condition)(memberOf)=or-group

How do I manage multi-values within the CONTAINS condition, for a query like the following one?

Retrieve all articles with title that contains (“MyKeyValue” AND “AnotherKeyValue”) or subtitle that contains (“MyKeyValue” AND “AnotherKeyValue”)

I tried to pass multiple values in this way, but it doesn’t work.

filter(title-filter)(condition)(operator)=CONTAINS
filter(title-filter)(condition)(value)()=MyKeyValue
filter(title-filter)(condition)(value)()=AnotherKeyValue
