Dear Mary Sue and others, I've been trying to use Mary Sue's search formula, +[pbs] [search terms] site:///lists.ibiblio.org on Google today without much success. Even when I used the example given, i.e. searching on the word fertilizer, I got only 46 hits instead of the 261 Mary Sue reported. I also searched on words which I'm sure I've seen in pbs postings, but without finding any. Does anyone have any idea what I am doing wrong? I've played around with the spacing, I've copied and pasted directly from Mary Sue's email, I've monkeyed around with the search terms: so far, very little success. Jim McKenney
