I now have my indexer working on albums and photos in the photo gallery. It needs some additional features, but it’s functional. So now I have indexing and searching for my HTML content, php content, blog posts and photos. This should be sufficient to get me by for a while; I’ll tweak it as needed.
The indexer (dwmsiteindex) uses a configuration file that permits skipping some directories when searching for HTML and php content. It is also used for database settings for the blog database and the gallery.
