+# Minimal Reproducible Example
+
+A search query with only subtraction should show all the elements in the
+gallery minus the subtracted elements.
+
+## Reproduction steps
+
+1. Search for `-france`.
+
+## Expected result
+
+`berlin.md` should appear in the results.
+
+## Actual result
+
+The search yields no result at all.
+
+## Version info
+
+Bug present in ldgallery v2.2.

+# Minimal Reproducible Example
+
+Having two or more similar tags which differ only in their casing results in
+the lowercase variant to be inserted instead of the other ones.
+
+## Reproduction steps
+
+1. Type `Test` in the tag input box and press enter.
+
+## Expected result
+
+The tag `Test` (starting with a capital letter) should be added to the search
+query.
