1) What do I need to check to fix Search?
2) Where can I learn more about SharePoint Search? Sites? Books? I need to become a search expert to maintain a high grade Intranet.
3) I launched a new public facing site with a separate SharePoint Web App (but on the same single-server farm as my Intranet) so how do I get Search to query only that Web App for Visitors (assuming I can fix Search from question #1)
