delete boundary

1. support delete in all indexes @dl239 plz check it
2. desc update, after 082, support ts range delete, still delete in right indexes, not all
give some examples. zh version desc is confused, can't delete all index
En version say delete the data in specific index, it's ok.

The issue mentions delete support in indexes and ts range delete after version 082. Look for index deletion logic in the codebase, possibly in index management files. Check the documentation for version-specific changes and examples. Determine which indexes are 'right indexes' versus 'all indexes' for ts range deletes.
