You can enable attachment indexing for a table so text searches can return matches
from the record and its file attachments.
Pourquoi et quand exécuter cette tâche
By default, attachment indexing is enabled for the Knowledge Base. You can enable attachment indexing for other tables.
Enabling attachment indexing causes the platform to reindex the selected table, its
parent table, and any children of the parent table. For large tables, such as the Task
table, reindexing can take several hours and slows down the system until complete.
Reindexing is best performed during non-peak times.
