Possibility of adding meta description to harvester engine settings ?

Hello,

i have a new question. 

Is it possible to use the “Aditional header / settings”  optin in the harvester setitngs to also grab meta description/ or meta title  when harvesting urls?

And can i display it (the description) in the main window?

Why –  in my experience it is MUCH easier to understand if a site is or is not relevant from URL AND meta description than from just url alone.
so, its way faster to filter out bad results.

thanks.
