Subject Re: Facet on a Payload field type?
Date Thu, 24 Aug 2017 00:47:53 GMT

: The payload idea was from my boss, it's similar to how they did this in
: Endeca.
	...
: My alternate idea is to have sets of facet fields for different languages,
: then let our service layer determine the correct one for the user's
: language, but I'm curious as to how others have solved this.

Let's back up for a minute -- can you please explain your ultimate goal, 
from a "solr client application" perspective? (assuming we have no 
knowledge of how/how you might have used Endeca in the past)

What is it you want your application to be able to do when indexing docs 
to solr and making queries to solr?  give us some real world examples



(If i had to guess: i gather maybe you're just dealing with a "keywords" 
type field that you want to facet on -- and maybe you could use a diff 
field for each langauge, or encode the langauges as a prefix on each term 
and use facet.prefix to restrict the facet contraints returned)

XY Problem

Your question appears to be an "XY Problem" ... that is: you are dealing
with "X", you are assuming "Y" will help you, and you are asking about "Y"
without giving more details about the "X" so that we can understand the
full issue.  Perhaps the best solution doesn't involve "Y" at all?
