Over the past few years I've worked on a number of websites, but mainly they've only had a limited number of pages, and I've never needed a site search facility.
With two of my more recent projects that has all changed and they now have a lot of content in them that needs to be searchable by a user.
I could just use Google's free stuff, and that is one option, but I would much rather implement a search that returns results within the web's layout from across all the site's content; just like the Channel9 forum search does in fact.
So far I can see that Index Server is an option, but before I get into any depth on this, I'd prefer to know if there are any simpler/better options.
The sites in question are running on W2K IIS5, so I'd appreciate any pointers as to where to start looking to implement a decent site search facility.
