Show which fields are being searched in Admin change_list's `search_fields`

[Ren de la Cruz]

In any Django Admin change_list pages, when including a search_fields attribute, the search bar does not indicate which fields are searchable. This can easily be confused with attributes on the sidebar list_filter.

Maybe something like a greyed-out caption indicating the model fields included in search_fields.

Hello RenDelaCruz, thank you for your interest in making Django better.

I can relate to your report, and I can see value in a small help text below the search box. I'm tentatively accepting to see how this would look like in the UI, are you available to propose a PR? We would love to count on your contribution for this!

We should definitely consider the accessibility aspects of this, but IMHO as long as the adding is equivalent to form fields help text, this should comply with all the accessibility requirements.

Yes, this can be quickly added as a small help text below (a minor change in template only) and I tried that. But what about values like user__email, name__exact, ^question, @descr, etc? We may need to use verbose equivalents for each queryset lookup or its shortcut, because the admin staff may not have technical knowledge to understand them as they are given. What's the suggestion?

[Jakub Szafrański]

If we aim for readability, perhaps it would make sense to resolve the fields and use field labels (if present) and some verbose text explaining what lookup is used?

Having many search_fields and/or fields with various lookups can lead to a potentially long help text which might hinder readability, so perhaps using some icons would make sense.

I can have a look at it and experiment with various formats so we can decide

I think it's quite rare to have a help text that goes deep into the specifics of what is searchable and what isn't.
We don't have an icon on columns when filters are applied, or text highlighting of searched text we found (which are more common UI patterns).
I think going into the specifics of search in the user interface is not worth it. Most people "search" to find out what the search does.

[Natalia Bidart]

I see your point Sarah, thanks for sharing your view on this matter. While I think it would be a nice addition to have a descriptive help text under the search field, I agree this may need a wider discussion and a higher level design that would consider other UI elements.
