The current implementation is a list of versions. So a search would show all versions that have the search parameter. For my purposes I'm interested in the date and time when change the occurred. It's an audit trail. Some people will want to recover the lost content.
If this was to be taken to the natural conclusion, the history would be displayed as a list of changes rather than as a list of versions.
For example "this is a sentence" deleted in version date-time, and "new text" added ... etc. I don't see any value in reporting any changes other than text, images, etc.
The version is not very helpful to me. It's the content or the change that is important.
