Applications such as this wiki (mediawikiruns 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. Note that However, 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 to directly search these applications. The MediaWiki system now includes as a Ajax 'suggest' "feature while you type in the search box. Setting " that is a UPO or User Preference Option that you control independently tacked on to each application in your user settingsstack.

If you're There is a sysop series of articles about the introduction of Full Text Search (FTS) in InnoDB engine for a MediaWiki site, you probably want to install the [[wmMySQL 5.6 at https:Extension:Replace_Text]] so that you can //www.percona.com/blog/2013/02/26/myisam-vs-innodb-full-text-search and replace strings -in your content.-mysql-5-6-part-1/

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.
