How can I show parent and child terms in facet search filter block for a taxonomy field having simple hierarchial select as widget type I am using facet filter to filter views values . I have a taxonomy term using widget type [Simple Hierarchial Select][1]  . I want to be able to filter parent and child terms both in facet filter block

Tax A
-- Tax A child
---- Tax A child of child

I want to use each one of the above as a filter in the facet filter block

How Can I achieve it?

I have ticked 'index hierarchy ' but it just shows the deepest term e.g. "Tax A child of child"

http://example.com/admin/config/search/search_api/index/*server name*/workflow
I'm presuming you are using FacetAPI and Search API Solr.

You need to add some settings to the facet itself at Search API > Index > Facets > [Taxonomy name]:
http://example.com/admin/config/search/facetapi/[indexname]/block/field_[taxonomyname]/edit

You'll need to 


Expand the hierarchy
Treat parent items as individual facet items
Don't flatten hierarchy
and minimum count zero (ie: show even when empty)
