Hey everyone, I field documents by "title" and "body". The title field often has far fewer terms than the body field. IDF, as a result, will have a profound effect in the title field compared to the body field.
I currently have the title field boosted by 4x relative to the body field. While I want matches in the title field to result in higher scores than matches in the body field, I don't believe I want the title to completely trump the body. I've seen this happen when a rare term is present in the title field, and IDF combines with the 4x boost to wreak havoc. I'd like to get your thoughts on the following: - Is it standard practice to avoid boosting the title field much, because of the (generally) high IDF of title field terms? - Are there other strategies for handling the high IDF of a title field?
