Hi, Lets say I have thousands of Lucene documents which have a FacetField which has the format of the following.
doc.add(new FacetField("Category", "level0", "level1", "level2", "level3", ...)); "Category" is the dimension name. "level0" represents the first hierarchical level, "level1" represents the second hierarchical level of "level0" (or the immediate children of "level0") and so on.. How do I get the top "level0" values of "Category" which will have highest number of unique "level1" values along with the unique "level1" count? Thanks, Gimantha
