> Opening this issue on behalf of [~mattweber], who reported this at https://discuss.elastic.co/t/es-7-7-1-es-7-12-0-wand-performance-issue/272854.
> It looks like the fact that we introduced dynamic pruning for queries that already have a minimum number of SHOULD clauses configured makes things _slower_, at least in some cases.
