I've been trying to find a way to unite all of my sites, blogs and galleries. One of my main problems was finding a decent search engine. Google is great, but I needed something that would go deeper.
Years ago, on a different server, I used one called FreeFind search engine I was still new to the internet and used just the basics. Now I'm taking advantage of many of their features.
With the search box on the Start page you can find exactly what you need. An index and sitemap will be added soon. These will give you a better idea of what to expect.
