+/**
+ * This Processor takes a UID of sys_category, and resolves its rootline in solr notation.
+ *
+ * Format of this field corresponds to http://wiki.apache.org/solr/HierarchicalFaceting
+ *
+ * Let's say we have a category with uid 111 which is a sub category like shown in this tree:
+ *
+ * 1
+ * |-10
+ *   |-100
+ *     |-111
+ *
+ * then we get a rootline 1/10/100/111
+ *
+ * In Solr hierarchy notation, we get
+ *
+ * 0-1
+ * 1-1/10
+ * 2-1/10/100
+ * 3-1/10/100/11
+ *
+ * which is finally saved in a multi-value field.
