When users are in a course and open the modal to pick library content to insert into their course (either as regular linked content or as part of a randomized problem bank), we want them to be browsing the published version of the library, not the draft. But this is a challenge because our search index currently only has the draft version.

^ The above view should show the published version.

Notes

The studio search index has always only included "draft" content because the original use case (searching course content in Studio) never needed to search published content. And most of the new libraries features don't need that either - except this one workflow.

We can easily exclude "never published" content from the search results already. The problem is displaying the old version of content that was published and then changed, but those changes haven't been published yet.

We can always show the correct (published) version in the Preview by requesting the backend render the published version 1. The problem is more the search results.

Suggested solution

Add display_name_published and description_published as new fields in the studio index. When (re-)indexing a library component, fill those in with the last published name and/or description.

Note: currently the "description" is generated on the frontend from content but we should generate description and description_published on the backend that same way.

Then, we can update the frontend to show either the draft or the published version in search results depending on the context.

Post-sumac we may also need a problem_types_published to avoid an edge case with capa problems that change type, but we can fix that later.

We don't have to store this data for the course blocks in the index; only library content.

As an optimization, when we know that the published version is the same as the draft version, don't bother "properly generating" the _published variants (e.g. don't call index_dictionary() on the published version) - just set them equal to the draft version immediately (or leave them blank - see below).

Open Questions

Should we store display_name_published and description_published in all cases, or only when they're different from the draft display_name/description? Doing the latter might make the index slightly smaller and searches slightly faster, even though it makes displaying the published version of the cards more complicated.

How will this work with keyword search? Is it possible to search specific fields in the "normal" (draft) view, and search other fields in the "published" view? i.e. normally we search display_name+description, but sometimes we search display_name_published+description_published.

@ormsbee @kdmccormick @pomegranited Does this plan make sense for how to deal with the need to sometimes show a search results view that only shows published stuff?

Sure, this approach seems fine for this.. are there any other use cases of this data?

Add display_name_published and description_published as new fields in the studio index. When (re-)indexing a library component, fill those in with the last published name and/or description.

What about searching the published html/capa content itself? We can store a "published" version of that content field too.

Will the frontend also need to know the full published usage key (including the published version), so we know which version this linked component is referencing?

So maybe it would be clearer if we nest these fields together like we do with tags? e.g.

   "published": {
        "display_name": ...,
        "description": ....,
        "content": ...,
        "usage_key": "<usage key with published version>",
   }

Should we store display_name_published and description_published in all cases, or only when they're different from the draft display_name/description?

I'd rather always store these fields even if they're the same... but I won't die on this hill 😄

I'm proposing having that data summarized in the description[_published] field by the backend during indexing, and we don't currently have any other use for content. So for now I wouldn't bother.

Will the frontend also need to know the full published usage key (including the published version), so we know which version this linked component is referencing?

No. For v2 libraries, I designed the opaque keys so that they don't have version or branch fields. In my opinion, having several different keys for the same piece of content depending on the context made the modulestore code very messy and was responsible for a variety of bugs. For v2 stuff, we're specifying draft vs. published vs. specific versions via separate parameters, not as part of the key.

So maybe it would be clearer if we nest these fields together like we do with tags? e.g.

Up to whoever implements this, but I think that looks nice.
