Describe the bug

Steps to reproduce

Expected behavior

If the command flag doesn't exist, it should not be mentioned within the service documentation.

The above command throws:

$ opencloud search index --all-spaces --force-reindex
Error: unknown flag: --force-reindex
Usage:
  opencloud search index [flags]

Aliases:
  index, i

Flags:
      --all-spaces     index all spaces instead. This or --space is required.
      --force-rescan   force a rescan of all files, even if they are already indexed. This will make the indexing process much slower, but ensures that the index is up-to-date using the current search service configuration.
  -h, --help           help for index
  -s, --space string   the id of the space to travers and index the files of. This or --all-spaces is required.
