It will help if your database has been runing for a very long time

 This will display statistics about your command usage, such as the most frequently used commands, options, and arguments.
 
+For database maintenance (recommended to run if you notice performance issues):

+```fish
+$ based maintenance

+This will optimize the database by running VACUUM and ANALYZE operations to keep it performing well.

 ## Configuration
 
 You can customize the behavior of based.fish by setting environment variables in your Fish shell:
 
 - `BASED_NO_CONFIRMATION`: If set to `1`, automatically executes the selected suggestion without confirmation, otherwise, it requires another Enter key press to execute the suggestion.
 - `BASED_NO_FUZZY`: If set to `1`, disables fuzzy matching for completions and only commands that start with the typed prefix will be suggested.
+- `BASED_EXCLUDED_PATHS`: A list of path patterns to exclude from history logging. Supports glob patterns like `*` and `?`. Useful for excluding temporary directories, sensitive locations, or paths where you don't want command history tracked.
