**Steps to replicate the issue** (include links if applicable):
* In `zh` wiki, request the following API to get a list of articles that include their description from wikidata or the content from the articles.
https://zh.wikipedia.org/w/api.php?action=query&exchars=100&exintro=1&explaintext=1&formatversion=2&generator=search&gsrlimit=3&gsrnamespace=0&gsrqiprofile=classic_noboostlinks&gsrsearch=morelike%3A%E8%8F%B2%E5%BE%8B%E8%B3%93&origin=*&pilimit=3&piprop=thumbnail&pithumbsize=160&prop=pageimages|description|extracts|info&format=json&inprop=varianttitles
**What happens?**:
The `description` or `extract` only provides one result instead of results for different language variants.
**What should have happened instead?**:
The `description` or `extract` should either provide the following:
1. A list of results for different language variants, similar to `varianttitles`.
or
2. Output the correct result based on the URL request's `Accept-Language` header or a possible language variant parameter.
