solr core, which one active, flip or flop ?

Hello Everyone, I understand, when we have two phase indexing setup, we get two cores; flip and flop. But when we do search in storefront, which one is accessed in solr ? When I go to solr admin console, I see both the cores are current. When I run indexing (delete in my case), in one environment I see flop is getting updated, and in a other environment, I see flip is getting updated.

Attaching the screenshots.

Thanks in advance.

Try this flexible search to see which core is active for each config

 select {solrfacetsearchconfig.name},{solrindex.qualifier}
 from {solrindex join solrfacetsearchconfig on {solrindex.facetsearchconfig}={solrfacetsearchconfig.pk}}
 where {solrindex.active}=true

It indexes the non-active one and then switches them over to search that freshly indexed one once complete. The old active one is then non-active and ready for the next indexing run.

Thanks a lot Andrew. This is exactly what I was looking for.
