Find paragraph by using that text located in

I need to search paragraph by giving paragraph heading text associated with it and to which some heading are set like wdOutlineLevel1, wdOutlineLevel2. 

For example:

Feature A

paragraph text- A chip is a major building block of an electronic system such as an ASIC or an FPGA.

I want to find the above paragraph by giving only "Feature A" without iterating on all paragraphs of the document.

I have set "heading 2" for text "Feature A" and "paragraph text-......" is the normal text.

Any help will be appreciable.
