排除solr中的构面字段

Question

Its a badly inserted data in solr which is the issue but is there way to fix the below scenerio.

"Attributes": [
      "Width=680 mm",
      "Height=990 mm",
      "Type=Recycling",
      "Color=White"
      "Size= L"

    ]

At front-end, all of the above fields are grouped according to key of the attribute , user can select any one of them.

There would be no issue at all if the above data would have been inserted as separate fields against a document(i can not change that). I could have easily exclude the facet field to show the count of the other related attribute. For example when user select Size L, i could show the result for XL and S.

But with this above data, its not possible to exclude correctly in case user select 'Color' and 'Size' at the same time.

Any suggestions?

This can be achieved through tagging and excluding. You tag a filter and exclude them while building the facet counts. In your case

select?q=*:*&fq={!tag=pr}size:L&facet=on&facet.field={!ex=pr}size

You can do it for multiple facets too. Hope this helps.
