Description arcasys 2025-11-20 00:18:56 UTC 
SUMMARY
Duplicate search (100% similarity) does not list results. If a sub tree of albums is searched for exact duplicates the number of duplicate items is found but no items listed.

STEPS TO REPRODUCE
1. Choose Similarity
2. Set Similarity range to 100% - 100%
3. Search in all albums
4. Select a sub tree of albums

OBSERVED RESULT
If all albums are selected all 100% duplicates are shown.
If only a sub tree of albums is selected, no 100% duplicates are shown. This seems to depend on the number of selected albums - manually selecting all and deselecting a single album worked as expected - but most of the time it did not work. 

EXPECTED RESULT
100% duplicates should be shown non respecting the choice of albums.

This was a wrong observation. The feature works as expected.
