CompletionSuggester: crossnamespace redirects should be ranked lower
Closed, ResolvedPublic
Actions

Description

Support for crossnamespace redirects was recently added to the completion suggester, unfortunately it causes weird behavior for some prefix on enwiki.
Searching for mos will flood the search suggestions with various set of redirect shortcuts to the Manual of Style.
We should maybe rank lower crossnamespace redirects in the completion suggester so that content pages have a chance to be suggested.

On the one hand, this is a serious degradation. On the other hand, it only affects a very, very small number of queries. This should be fixed ASAP.
