Personalized search engine on your website

This is especially useful if your site has many pages and access to content is difficult, and it complements the site map. The site map is addressed to search engines, and the search field is addressed to visitors. And you will use Google's algorithm and all its enhancements to find information on your site!
This widget is used by major sites such as the New York Times or MacWorld.

On the anniversary of the three years of the service's existence, Google brought several developments described in the personalized search blog. It provides the following new features:

• Specialized research topics.
  Select a results view page from the topic list.
• Structured user search.
  A more sophisticated approach to structured research requires providing meta-data to the engine.
• Wikipedia research.
  Replace the wiki engine with Google .

Google provides JavaScript to place on your pages to display a custom search field. This script is generic, but can be configured online after signing up to Google.
You can also use the form to enter a site URL to check search results.

Custom Search and Adsense

If you have an Adsense account, a custom search box can be combined with your show program and search results on your site will be supplemented with ads.

• See the Adsense tutorial.

For the company

A paid service is also offered, the cost of which depends on the number of pages and annual requests. This service allows the webmaster to weight searches based on date, as well as maintain parts of the site.

• See Google Site Search.

Search by link

The difference from the standard version is that the definition of the search engine is posted on your website, and not on the online Google.com/cse service, where it needs to be determined.
The search itself is always performed by Google, the URL of your site is sent to it by a specialized search script.

The advantage is that you can create several user engines, for different pages or different users.

• See Google documentation.

Wikipedia

Personal search should now be built into Wikipedia with the option for the user to replace the Wikipedia search tool with a Google tool.
He allows him contextual search: information is aimed at the content of the current page.

• See Wikipedia, the most controversial site on the web.
