Example doesn't work

Besides for the " (double quotes) in the query examples given I couldn't get the second query to work without adjusting it SELECT candidate_name,SSN FROM candidates WHERE CONTAINS(candidate_resume,”SQL Server”) AND candidate_division =DBAto this:SELECT candidate_name,SSN FROM candidates WHERE CONTAINS(candidate_resume,'SQL AND Server') AND candidate_division =DBAAfter the adjustment it did work (of course "and" can be "or" as well).
