Yes what you are thinking is correct.
For example consider string “google”.
Then prefixes are

g

go

goo

goog

googl

google

Is google also a prefix?

Thanks, can you also clarify this statement : " there should be a filter that contains the name of blocked site(filter is a prefix of blocked site)." How can a filter contain name of blocked site ? for example in google the name is google

I think that was a typo.Read first 3 lines of the 3rd paragraph carefully.
