Reconfiguring the search property list of the full-text index has truncated the existing data in the index. Until the full-text index has been fully repopulated, full-text queries will return partial results. The ALTER FULLTEXT INDEX  SET SEARCH PROPERTY LIST ...; statement automatically issues a full population, but if the ALTER FULLTEXT INDEX statement specified the WITH NO POPULATION clause, you must run a full population on the full-text index using ALTER FULLTEXT INDEX ON  START FULL POPULATION;. This is a warning.
