| − | + | When searching for unrestricted graphics content, it is hard to beat the huge commons of Wiki commons. Use the search engine on toolserver.org to find the images or other media you're looking for. http://toolserver.org/~tangotango/mayflower/ Any image found there can be used under the terms of the (creative commons) license listed -- meaning it can be used here or on your website. | |

| + | Applications such as this wiki (mediawiki), and CMS systems (e.g. Drupal) obviously know their own content. So, if you are looking for something and want the best results for those applications, you should make use of the direct search facilities in the application. Note that this wiki and the CMS systems also provide an 'OpenSearch' implementation that lets you use your browser's search toolbar to directly search these applications. | ||
| − | + | The MediaWiki system now includes a Ajax 'suggest' feature while you type in the search box. Setting is a UPO or User Preference Option that you control in your user settings. | |

| + | # The Lucene backend used on Wikipedia [[mw:Extension:Lucene-search]] can be used for large-scale installations where the built-in search is not sufficient. Note that the simplest enhancement you can make to a small-scale installation is to tweak the MySQL stopwords and word-length. | ||

Google offers a service called the [http://www.google.com/coop/cse/ Google Custom Search Engine]. The Google CSE is much like the 'normal' Google, but is configured to include only domains that you want. Additionally, the domains can be grouped into 'realms' that can be used to assist the user to find content according to functional area. | Google offers a service called the [http://www.google.com/coop/cse/ Google Custom Search Engine].

Meanwhile, [http://kohsuke.org/ Kohsuke Kawaguchi] the magic man behind Jenkins (Hudson), also wrote [http://sorcerer.jenkins-ci.org/ Sorceror] which understands semantics in Java. Sadly, Sorceror code hasn't been touched in 4 years and doesn't seem to be an active project - but for Java codebases, it's probably still a good option. |
