How can i take plain query from user and sepate it with OR operator?

SELECT plainto_tsquery('english', 'user query');

output:

"'user' & 'queri'"

but i need something like that:

"'user' | 'queri'"

to_tsquery is not suitable for me, websearch_to_tsquery almost the same.

Also I’m using SQLAlchemy, maybe there is something that can help with it
