Hi Krishna
It is not possible in SSA 12.1 to customise the way the address search works.
However in SSA 12.2 (due end of April) we have added the ability to create your own UI components which can be added to SSA. One code example we have created to showcase the capability is a custom address search component which does what you ask. It replaces the regular address search component but instead of searching addresses it lets the user search against 3 feature tables and shows the results. Once user selects a feature from the results the selected feature is then shown on the map as a highlighted polygon.
I am not sure if you have had access to a pre-release of 12.2 already? If not we can provide the docs and sample code on how to create your own extensions. These are in draft form at the moment.
