I haven't been able to reproduce Solr not making the delete call, and given
that the code is the same between ES and Solr, I'm inclined to call it a
browser issue.
I have spun this back up for both ES and Solr (with the caveat that the
default "source.type.field" for ES is broken until master is merged all the way
down.
At this point both work, after a minor fix that would result in an off by
one error in the UI when deleting. The UI is functional for both, although
with the previously mentioned preexisting latency issue in updating, I do
recommend closing and reopening the tab or things don't line up correctly.
At this point, the only issue is the indexString.
