It has been searching just .txt [text] files. It now searches Adobe's .pdf files. To search 'just" the .pdf files inurl:pdf FAGLEY or whatever. Searching it for FAGLEY, I found several times cousin Bob Fagley's NANCY,PhD at Rutgers,and cousin Bill in Midland,Mich, and Dad's cousin Rev Fred Fagley's "History of Congregationalism". I'm not sure why Adobe's .pdf format is used. Just that I've downloaded Adobe's reader of .pdf files in the past. I guess it's an Internet format.
