Original ticket: T102464
If the search api reports an error (e.g. "search backend too busy"), the app shows a misleading "No results found" and doesn't show the info reported by the api. This should be fixed, we had some tickets in our OTRS support queue, because of a search backend failure (related T102463 and [[ https://wikitech.wikimedia.org/wiki/Incident_documentation/20150615-Elasticsearch | the doc of it ]]) with the question, why all search queries reports, that there aren't matches.
The api response was (i remember, that we're using search and not prefixsearch anymore, but i'm not sure :)):
```
{
"servedby": "mw1121",
"error": {
"code": "srsearch-error",
"info": "Search is currently too busy. Please try again later.",
"*": "See https://en.wikipedia.org/w/api.php for API usage"
}
}
```
