I dont think that yahoo has indexed your site.
if I do a search using yahoo, it does not find any results:
search?n=10&ei=UTF-8&va_vt=any&vo_vt=any&ve_vt=any&vp_vt=any&vd=all&vf=all&vm=p&fl=0&fr=yfp-t-892&p=government&vs=www.dutyone.com%2F
The Search for BOSS uses the Yahoo index of your site to return results.
