Yonik Seeley commented on SOLR-764:
-----------------------------------
bq. How is the refinement different?
The lists are merged by sorting, then a window is selected to return.
For facets sorted by count, the counts (and thus the order) may not be correct.
Facet terms outside the window may actually be inside the window (or above it,
changing the order). The code calculates what terms (out of all those
returned) could possibly change what the window looks like, taking into account
the maximum value it could have for each shard based on what it saw from each.
For facets sorted by index order, the window into the list will not change
based on any facet refinements. Actually, we should remove any amount of
"over-requesting" when sorting by index order. The counts could be off
though... we may not have the counts from certain shards. So we only have to
request counts when:
- the term is in the window to be returned
- the term is missing from a shard, *and* that term comes *after* the last term
the shard returned.
