Full-Text Index Modified After Transaction Log Backup
When restoring the transaction log of a database, you might see a warning indicating that the full-text index is not in a consistent state. The reason for this is that the full-text index on a table was modified after the database was backed up. To bring the full-text index to a consistent state, you must run a full population (crawl) on the table. For more information, see Full-Text Indexes.
