Index time sorting and per index mergePolicyFactory

Hi,

I know this is done in lucene, but I don't see it in solr (by searching +
docs on collections).

I see
https://cwiki.apache.org/confluence/display/solr/IndexConfig+in+SolrConfig
but it's not mentioned for index-time-sorting.

So, is it possible and definable for each index ? I want to have some
sorted by 'x' field, some by 'y' field, and some staying as default.

Thank You

Wait, on the page you referenced there's this which appears to be
exactly what you want:

<mergePolicyFactory class="org.apache.solr.index.SortingMergePolicyFactory">
  <str name="sort">timestamp desc</str>
  <str name="wrapped.prefix">inner</str>
  <str name="inner.class">org.apache.solr.index.TieredMergePolicyFactory</str>
  <int name="inner.maxMergeAtOnce">10</int>
  <int name="inner.segmentsPerTier">10</int>
</mergePolicyFactory>

And since this is in solrconfig.xml which is defined per core you can
specify whatever
you want for each core.

Also see SOLR-5730 and SOLR-8621

Best,
Erick
