Thank you,
Nagore.
Yes, the syntax is right but I would guess, because you are asking, it
does not do what you think it does.

'300' is a string; it is not a numeric value of 300.
And also, the filter is never true!
FILTER (?p <= 300 && ?p >= '800')
How can ?p be less than or equal to 300 and also greater than or equal
to 800? It can't whether it's a number or a string.
Did you mean one of:
FILTER (?p >= 300 && ?p <= 800)
i.e. ?p in the range 300 to 800
FILTER (?p <= 300 || ?p >= 800)
i.e ?p is less than or equal to 300 OR ?p is greater than or equal to 800
