Jan Høydahl commented on SOLR-17215:
------------------------------------
Suggesters have never supported replication, especially for the dictionaries
that require explicit build. I thought it was documented but cannot find it. So
you either need to select one node to query or to build on each node.

> Following is the request to build the suggest dictionary:
> /suggest?[json.nl|http://json.nl/]=flat&omitHeader=true&suggest.build=false&suggest.reload=false&suggest=true&suggest.buildAll=true
>
> After successfully building the suggester dictionary, we encounter an issue
> with autocomplete responses. Autocomplete requests only succeed if they are
> routed to the replica where the {{/suggest}} command was executed. Otherwise,
> an error occurs:
>
> {code:java}
> java.lang.IllegalStateException: Lookup not supported at this time{code}
>
> I assume, the suggester dictionary only builds on the replica/node where the
> suggest command was executed and replication doesn't occur
>
> {Couldn't find anything in docs & also there was no help from mailing list}
