I have run into a quirk with the Search engine in Backlight. This probably affects very few sites but it does affect mine. The search algorithm is based on factors including the number of time a term is repeated in a given page as it should be. However, it results in an uneven weighting for album sets that are both based on Pangolin album but one is a slideshow presentation and the other is a single image presentation (Album->Photo Presentation->Presentation Type). For the “Single-image” type the browser is presented with (and presumably the search engine sees) a separate page for each image, while the “Slideshow” type present the browser with a single page listing ALL links to images in that slideshow (check this by looking at the Page Source). I believe this is results in higher priority for slideshow albums that contain multiple images with the same search term are prioritized over albums with single images. This is probably not a problem for most sites but on my site it means that slideshow images overwhelm the search results even to the point that my single image albums are not even displayed in the search results (only a limited number of all possible results are returned).
This behavior is the opposite of what I want. I need to prioritize my single image pages/albums/album sets in the search results above my slideshow/albums/album sets in the search results. I am perfectly willing to customize my site to achieve this but at least would need to have complete documentation on how the Backlight Search function is configured. If anyone can provide a lead to where that info can be found please let me know.
Matthew. I am NOT asking for the current search function to be changed. However, in some future update I suggest that this issue can be fixed (and the search function drastically improved for everyone) if capability could be provided to prioritize album sets (or individual albums)in the search results. For example, Album Set A 100%, Album Set B 80%, Album Set C 10% as is pretty much standard in crawlers used for indexing web sites.
