Hierarchical Cut

Does anyone have experience implementing hierarchical cuts this way? See Link http://lucene.472066.n3.nabble.com/multi-level-faceting-td1629650.html#a1672083

What should the circuit look like?

(I would like to implement tree-cutting without using SOLR-64. The patch works well on the old branch, the only thing is that it does not fix the solo trunk.)

I have no experience with the specific solution described in the mailing list, but during my last research in his field I came across Solr Bobo Browse . It also supports hierarchical cutting and seems quite mature.

Solr, , . , category.

XML- :

<field name="category" type="string" 
                               indexed="true" stored="true" multiValued="true" />

, , , :

<category>1_sport</category>
<category>2_watersport</category>
<category>3_scuba_diving</category>
