Please teach me what is the job that "Regenerate Text Indexes".
Is it possible to run this job at a specific time (such as midnight)?

The documentation is pretty good: https://docs.servicenow.com/en-US/bundle/tokyo-platform-administration/page/administer/search-admini...

By default, the system maintains text indexes on a daily schedule. Typically, you only need to manually regenerate a text index when you change these values.

• You change the list of table-specific stop words.
• You change the display value of a record such as changing a user or group name. Until you regenerate the index, text searches for old display values will still produce results and searches for the new display value won't show results.

You can also regenerate a text index if you observe incorrect search results for the indexed table. This is rare and usually only occurs if text indexing was interrupted.
