Thank you Erick for your prompt response. I'm sorry I could not get back to you earlier.
My current setup does not use the ImageUrl field for the search (more specifically as the default search field). The ImageUrl field contains a URL to the image which is for most part a GUID, which is meaningless to users. However, I would like to note that the ImageUrl field is Indexed and Stored. I'm curious how should I use tf() for the boost. On the face of it, it seems to be what I want, but I cannot figure out how to use it. Similar to my example in my original post: &bf=log(qty) I cannot do: &bf=tf(ImageUrl,field(ImageUrl)) I think it is having a problem with field(ImageUrl). If I replace it with something static like ' http://domain/pathtoimage.jpg' then it works. However, I would like it to have the value of the ImageUrl field instead of this static value. As I mentioned in my original post, I would like to boost unique images. The image URLs are not part of the search terms. tf() seems to be what I am looking for, if I can get the current ImageUrl field value into the function. Thanks again, O. O.
