Thanks its working. But one new problem.
When searched for particular Taxonomy, products associated to it is displayed, but actual taxonomy with product count in bracket is not displayed.
Say product category taxonomy named ‘Product-Category-1’ has 2 different products ‘Product-1’ & ‘Product-2’. When searched for ‘Product-Category-1’, ‘Product-1’ & ‘Product-2’ are displayed but actual ‘Product-Category-1’ with Product count is not displayed.
