Photoshop Elements :: Selecting Only Best Matches In Result Of A Search With Stacks / Version Sets

One thing I don't like when you do a search and some results are included in stacks of version sets, it that you are shown the best matches with the non matches indicated by a special icon. Then you can't have the option to 'select only best matches'.

An example : Suppose you usually shoot raw and keep only the best edited jpeg in a version set together with the original raw.  You want to delete the original raws when there is an edited jpeg in the version set. You can perfectly use the search by details for files in a version set and filename with the raw suffix.
 
How can you select only the 'best matches' in the result of the search ? Unless there is a way to do that easily, I would like to introduce a feature request to add 'show only best matches in stacks/version sets' in the option menu of the result of the search.
 
You could :
- select all the results and expand all stacks and version sets
- assign a temporary keyword like 'IsInVersionSet' to all
- do a new search by detail for 'IsInVersionSet' and filename ends with raw suffix
- Select all and delete
- remove the temporary keyword.

That would work for version sets with only one original and one edited jpeg, not for multiple files in a stack or version sets, the info about stacks or sets would be lost.The only method I have found to do the selection and deletion with keeping stacks and version sets is:

- create a catalog copy (copy of the whole catalog folder)
- in the new catalog, use the above procedure to delete the raws
- in the old catalog, find missing files and delete them from catalog.
