Please Find the attached SQL Zip File of the work i have done so far, if you are configuring this on your end; Follow Process-1 and Process-2 mentioned in this post.

I have posted the same issue at Port HS support for Taxonomy Views to Drupal 6, As per suggestion received from Wim Leersi have posted this again; so please won't mark this as Duplicate Item.

Expecting Favorable reply.
