> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Reporter: Chris M. Hostetter
> Priority: Minor
>
> This is a very atypical usecase that i doubt impacts any actual users but
> popped up when i was working on some randomized testing so i wanted to file
> it for general knowledge/tracking...
> * QEC typically only elevates documents if the sort starts with {{score desc}}
> * {{forceElevation=true}} is suppose to ensure that elevated docs appear
> "first" in the results, even if some other primary sort is used
> * in the -- very unlikely -- case that {{score asc}} is used as the primary
> sort, {{forceElevation=true}} does not work
