memory_rebuild_fts
Drops and rebuilds the full-text search index from the stored records.
local stdio server writes destructive idempotent
Caution. Marked destructive: the index is dropped before it is rebuilt, so keyword search is incomplete while it runs. Back up the database first on large stores.
When to use
- Keyword search misses records you know exist.
- After a database migration or a manual edit of the records table.
- The index row count does not match the number of records.
Parameters
This tool takes no parameters.
