[TYPO3-Solr] Solr hierarchical facet

[Hemalata Jadhav]

Hello,
I am using EAP 2.7.1

I have 4 categories, each category has multiple sub categories
I want to add facet on these categories.

I need to display the main categories and their respective subcategories 
under it.
1) I have used hierarchical facet as below. This code just displays 
label of facet "Categories" and no categories / subcategories. If I 
remove hierarchical facet TS it shows the categories (no distinction 
between categories and subcategories) in "descending order" of highest 
number of news in a category/subcategory.
Question: What is  the solution for this and what can be wrong in the 
below TS. Empty facets (categories) are not shown. I want those to be to 
also appear.

2) As I want date-range facet where start and end date will be selected 
and on-click of search results should be filtered. With below code I get 
list of dates displayed as "2012-06-13T17:11:49Z (1)".
Question:  is the TS missing some thing ? what configuration may be 
checked to get the desired result ?

3) Question: there are news related to micro-sites (micro-site in under 
main root) and while I am on a particular micro-site I need to list only 
the news of that micro-site. How to configure this?

4) Question: I need to restrict a user group to see some news which is 
paid content. How to I configure paid content.
5) Question: Also I need to show in news result with the category to 
which it is related to?
6) Question: Is there any changes in template that i will have to do to 
get the desired view. Do we need to add some markers for this ?
