Google recently started their new Co-Op service (see [1] here) which allows users to create their own personalized search-engines to whichever topic they desire. More importantly, it allows for inclusion of the search into the website of the whoever created the search-engine. Especially the later is nice as before it was only possible to either drive the user away to the Googles’ homepage, open it in an iframe or a new window - all stuff that webmasters wouldn’t want for one reason or the other. I just created a [2] search-engine for machine-learning related materials. I’m still adding sites, but I’m getting better results for my personal searches already. I also wrote a module for the [3] PHPNuke content management system to include whichever personal CoOp search-engine you created into the system. You can download the [4] Search-The-Web-module for PHP-Nuke on my website. It even comes with English, German and French language-files (although the French translation might be a bit funny).
