It doesnt say "optimize = true" or that it will "optimize something". It says that your index is currently optimized. Thats a difference it describes only the current status of your index.

The best way to lookup this kind of thing is:

1. Insert a couple of rows
2. Lookup this value it will show "optimized"
3. Delete a row
4. Lookup again this value it will say "not optimized"
