[jira] [Commented] (SOLR-12490) introduce json.queries supports DSL for further referring and exclusion in JSON facets

["Mikhail Khludnev (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SOLR-12490?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16926538#comment-16926538 ] 

Mikhail Khludnev commented on SOLR-12490:
-----------------------------------------

I think we'd rather continue with adding yet another small cut. 

{code}
{
    "query" : {...}, 
    "params":{
         "childFq":[{ "#color" :"color:black" },
                    { "#size" : "size:L" }]
    },
    "facet":{
       "sku_colors_in_prods":{ "type" : "terms", "field" : "color",
          "domain" : {
               "excludeTags":["top",   "color"],   
               "filter":[ 
                      "{!json_param}childFq"  
               ]
           }
   }
}
}
{code}

Ideas are: 
* put json as param value, parser garbles it to meaningless string, but it's still available via {{req.getJSON()}}. 
* filter string invokes new query parser which convert json param as query DSL, need to decide how to keep {{JsonQueryConverter}} counter.   

Shouldn't be a big deal. Right?

> h2. Problem
> # after SOLR-9685 we can tag separate clauses in hairish queries like {{parent}}, {{bool}}
> # we can {{domain.excludeTags}}
> # we are looking for child faceting with exclusions, see SOLR-9510, SOLR-8998    
> # but we can refer only separate params in {{domain.filter}}, it's not possible to refer separate clauses
