[TYPO3-Solr] configure date range

[hemalata jadhav]

Hello,
I need to know how to configure to show tt_news with date range. i.e I want
two input box which will select a date "from" and "to" and only those news
with created dates will be in that range should be shown.

I dont know how its done. I just created a facet.

 plugin.tx_solr.search.faceting.facets.date {      field = created
 label = Date**     }
This gave list of dates, but I want two input boxes with date picker
and search button down. Onclick of search button it should search on
those dates.
Please help.

My 2nd question is i have categories in tt_news. On these categories i
need to search currently i did as followed:

 plugin.tx_solr.search.faceting.facets.category {      field =
category_stringM      label = Category**     }

There are subcategories for each category. And all subcategories are
listed. I want The parent category to be in heading and its respective
subcategory to be listed under :(

Thanks.
