I would prefer en ReindexCommand with option like this one

[loicmathieu]

I found it easier this way as you usually only reindex one type of data.

And this is an option (for the user); it's just as all commands will use a different repository I thought it would be better to have one command by object type.

But if you prefer I can have a single command that takes the object type as option.

I prefer to have some consistency and to avoid too many commands

[loicmathieu]

I move to a single command with a --type option to give the type of records to reindex.
