Subject AW: Re: Tagging and excluding Filters with BlockJoin Queries and BlockJoin Faceting
Date Tue, 23 Aug 2016 13:05:21 GMT
Hi Mikhail,

Thanks for replying so quickly with a suggestion.

I'm a colleague of Stefan and working with him on our project.

We tried composing our solr query with exclusion instructions, and the result was that the
facet excluded by tag did not show up anymore in the result, instead of showing all values.

Your example from the last comment, completed by our exlusion instruction:

json.facet={
  filter_by_children: {
    type: query,
    q: "isparent:false",
    domain: {
      blockChildren: "isparent:true"
    },
    facet: {
      colors: {
        type: terms,
        field: color,
        domain:{
          excludeTags:myTag
        },
        facet: {
          productsCount: "unique(_root_)"
        }
      }
    }
  }
}


and the corresponding filter query:

fq={!parent which='isparent:true'}{!tag=myTag}color:blue


Either this feature is not working yet, or we are making a mistake using it.
Of course we know it's still in development right now.

Might you please have a look if we are doing something obviously wrong?

Thanks,
Tobias
