Jan Høydahl commented on SOLR-13122:
------------------------------------
I’m ok with an alias with same name if it is 100% we’ll defined everywhere that
it is the alias that takes precedence. So if you have collection C1 with an
alias C1 pointing to the new C2 - how do you then query collection C1
afterwards, or issue a deleteByQuery or OPTIMIZE? Will a streaming expression
{{search(C1, q=foo)}} and SQL use the alias?
Now that we get rename of collections, there is of course a well defined path
to renaming old C1 to create the alias. Can that be done atomically?
Many questions here, suppose for the UI the simplest to do right now is to
prefix aliases in the url, say {{~collections/alias_C1}} to avoid clash, or add
a separate aliases menu as Gus suggests.

> After having recently toyed with Time Routed Alias in SolrCloud,
> we have noticed there is no way to query an alias from the admin UI,
> since the combo box only contains the current collection in the cluster.
> Solr Admin UI ought to have a way to query these aliases, for better
> convenience.
