+# 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.
+
+## Actual result
+
+The tag `test` (starting with a lower case letter) is instead added to the
+search query.
+
+## Version info
+
+Bug present in ldgallery v2.2.
+
+---
+
+Having two or more similar tags which differ only in their casing results in
+unrequested insertions in the query.
+
+## Reproduction steps
+
+1. Type `test` in the tag input box and press enter.
+2. Press the enter key or click on the "Search" button,
+   one or multiple times!
+
+## Expected result
+
+It should just search for items with the `test` tag and display the result.
+
+## Actual result
+
+The tag `Test` is added to the input field even though it was never requested.
+Trying to search again results in more instances of `test` and `Test` to be
+added to the search field.
+
+No result is found because the resulting "forced" search query is wrong.

+# Minimal Reproducible Example
+
+Multiple issues are shown with this example.
+
+---
+
+Incorrect related filters:
+
+Suggestions for related filters should only contain categories used in the
+items in the search result, not all categories happening to contain tags in
+the results which have the same name.
+
+## Reproduction steps
+
+1. Search for `animal`.
+
+## Expected result
+
+The related filters suggestions should only suggest `animal:bat`, but not
+`object:bat`, since the only result does not have `object:bat`.
+
+## Actual result
+
+Both `animal:bat` and `object:bat` are suggested as related filters.
+The latter is incorrect.
+
+## Version info
+
+Bug present in ldgallery v2.2.
+
+---
+
+Incorrect related filters:
+
+Excluding a category should result in all tags in that category being excluded
+from the related filters suggestions, even if they happen to contain a tag with
+the same name.
+
+## Reproduction steps
+
+1. Search for `-animal`.
+
+## Expected result
+
+The `animal` category should not show up in the related filters suggestions.
+
+## Actual result
+
+The `animal` category still shows up in addition to the `object` category.
+
+## Version info
+
+Bug present in ldgallery v2.2.
+
+---
+
+Incorrect search results and related filters:
+
+Excluding a category should only exclude tags in that category.
+It should not exclude items having a tag with the same name in other
+categories.
+
+## Reproduction steps
+
+1. Search for `-animal`.
