Feature request, for the search completion suggestor to automatically search cross-wiki, if given an interwiki prefix to start.
E.g. At English Wikipedia, typing "wikt:foo" into the search bar, would trigger search suggestions that come from English Wiktionary.
(Task based on proposal in https://meta.wikimedia.org/wiki/2016_Community_Wishlist_Survey/Archive#Cross-wiki_search_suggestions that is unfeasible in the short-term. Full copy:)
- Problem: It is possible to navigate, for example, from English wikipedia to the article about Argentina in Spanish wikipedia by entering "es:Argentina" in the search box, or to the English wiktionary entry about whatever by entering "wikt:whatever". You won't, however, be given search suggestions like when you are about to navigate to another page in the same wiki.
- Who would benefit: Users who are interested in several wikis.
- Proposed solution: Our search engine should learn that, if the text entered into the search box begins with interwiki prefixes as described here, search suggestions should be made from that very wiki associated with the given interwiki prefix.
