Want free graphics (as in Libre Graphics)?
When searching for unrestricted graphics content, it is hard to beat the huge commons of [https://commons.wikimedia.org/wiki/Main_Page WikiMedia Commons]. 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.
Flickr also has millions of images licensed under creative commons licenses: https://www.flickr.com/creativecommons/
=== Native (Application) Search ===
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 as a "feature" that is independently tacked on to directly search these applicationseach application in your stack.

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.
An example implementation can be seen at the OASIS search site http://search.oasis-open.org
The main limitations of the Google CSE are that
# The content must be public (can't be used for your private Intranet)
# The index will not cover an unlimited amount of content
# The index will not allow custom data formats or indexes that you create... it's Google's algorithms for better or for worse.
To meet these needs, use a product like [[mnoGoSearch]], [[mw:Apache Solr|Apache Solr]] or [[mw:Nutch]] which you are free to install and configure to suit your requirements.
See [[wp:Category:Internet_search_enginesInternet search engines|Category:Internet search engines]] for a list of search engine solutions.

=== Search your code. Can you 'grok' it? ===

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.
=== Browser extensions / Web Apps ===
* [[wp:OpenSearch]] is a standard for building search plugins, and exposing search services. It is how Firefox is able to hook up with wikipedia to offer suggestions '''as you type''' in the wikipedia search toolbar within Firefox. It is also how this site tells the browser that it offers a search toolbar plugin.

Opensearch is implemented in the mediawiki [[MediaWiki]] system.
