in many ways it sounds like a development of swish-e a search mechanism for web sites that is free software (originally on debian Linux but now windows and possibly Apple ) can be setup to search all the types mentioned – I use it on my own private copy of my web site (relatively small with just 15,000 html pages) but was blocked by the current hosts as being a ‘free’ Linux system their engineers were only comfortable with windows based systems
I did try the new forums search and it came up with what I wanted part way down the 5th page. Google gave it to me as the first item so not so useless in my book
The Google site-search [from the home page here] rarely works properly for me when searching for one of my previous posts … It often ‘knows’ that I posted it, but then directs me to the wrong page in a long list of pages.
