I think he is saying he wants to ONLY pull up threads with "Giambi" in the TITLE of the topic.
If so, this is different than the 5,000 returns for 'Giambi", because these 5,000 include all posts with Giambi somewhere in the text (like, one that ranks him in a list with 500 other players).
I have never been able to search based strictly on the title, either, so have given up searches. I think the ability to do so would be one of the single best improvements to the site. It's borderline worthless to get 5,000 returns for Giambi.
Does anyone know how to restrict a search only to the topic?
