Description

Many pages do not appear in typeahead search results (autocomplete / search suggestions).

For example: https://en.wikipedia.org/w/rest.php/v1/search/title?q=Kirby+and+the+Forgotten+Lan&limit=10 should return https://en.wikipedia.org/wiki/Kirby_and_the_Forgotten_Land as one of the results, but it returns nothing.

Very likely due to the opensearch migration

dcausse moved this task from Incoming to Done on the Discovery-Search (2025.05.02 - 2025.05.23) board.

Apologies about this, as part of T388610: Migrate production Elastic clusters to Opensearch (CirrusSearch backend infrastructure) we disabled some updates, some transition took longer than we expected. I routed the search traffic to codfw which should have fresh indices. The example query mentioned in the description now returns results.

Thanks to @Thesavagenorwegian , @matmarex and everyone else who reported this issue. I've opened an incident report here . If there are any missing or incorrect details, please respond here and we'll work on updating the report.
