A new Google tool will let people use Google's search platform to create search engines focused on the content of their choice.

With the Google Custom Search Engine, announced by the company on Monday in the US, Web site and blog publishers can provide custom results most relevant to their readers, incorporating a site's online community and its ability to provide contextual ads.

The customised search engines can also be tailored to aesthetically match any Web site.
