32682	Deleting objects after searching related many to many field crashes the admin page	Zain Patel	Mariusz Felisiak	"Minimal reproduction:

{{{
# models.py
class Post(models.Model):
  title = models.String(...)
  authors = models.ManyToMany(""User"", ...)

class User(models.Model):
  email = models.String(...)

# admin.py

class PostAdmin(admin.ModelAdmin):
  search_fields = (""title"", ""authors__email"")
}}}

then opening the admin site, opening the post page that contains only one post (any title and author assigned) and entering a search term (e.g the first 2 characters of the title), selecting the post and then using the delete action results in an Internal Sever Error 500 with an error/stack-trace:

I can confirm that `pip install django==3.1.8` fixes the error, and after having a look at the diff between stable/3.2.x and 3.1.8, I suspect the ""regression"" comes about from the work done on preserving the filters on delete or something along those lines - I haven't done a thorough investigation yet. Presumably `.distinct()` is being called because of the search involving the many to many field.
