+## If I had more time / What can I improve
+
+- Better object printing instead of using `spew.Dump()`
+- Reuse more shard logic especially in `search/index.go`, but due to Go missing generics concept it's different when compare to `Ruby`, `Java` and some other popular languages.
+- Add more tests, due to this code test costs me a lot of time to complete, so I didn't cover all the code currently, but I am keen to add more tests if possible.
+- Better user experience in CLI application, current the cli app is very basic and go can't go back to previous menu.
