Applications such as this wiki (runs on 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 usually it would suffice to make use of the direct search facilities built in to the application. # [[mw:Search]] helps you learn and understand the search capabilities of this system# Note that the simplest enhancement you can make to a small-scale installation is to tweak the MySQL stopwords and word-length. However, the built-in search capability of MediaWiki is actually not that great. See the section below on CirrusSearch Note that this wiki and the CMS systems also provide an doesn'OpenSearch' implementation t always ring true -- especially when you consider that lets you use your browsersearch as a service in it's own right is probably more powerful than search toolbar as a "feature" that is independently tacked on to directly search these applicationseach application in your stack.

LXR The [http://lxr.linux.no/ Linux Cross Reference] is probably the first widely used web-based code cross-reference tool. Along came [http://opengrok.github.io/OpenGrok/ OpenGrok] which started out as a project at Sun (which was bought by Oracle) and now the project lives on its own in the open. OpenGrok is '''lightening fast''' and is actively maintained as an open source project on GitHub. By the way, the underlying search is powered by SOLR. Meanwhile, [http://kohsuke.org/ Kohsuke Kawaguchi] the magic man behind Jenkins (n�e 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.
