Publishers making changes to their site content have the option of manually updating the site index, thus making new content immediately accessible via Site Search, following an update from Google.

Site owners must visit the configuration screen for their Site Search and hit the "Index Now" button, and a fresh crawl will be done of the entire site. Data is then made available in real-time to anyone conducting a search within the destination.

That the new tool does not provide on-demand indexing for Google's general index. Beyond their own sites, publishers must still wait for the Googlebot to visit, locate changes and incorporate them into Google's index.

Last year Google introduced custom search tool for businesses, priced at $100 a year for searching up to 5,000 pages, and $500/year for up to 50,000 pages. The service includes business integration features, the option to turn off ads and email and phone support. View a service demo:

In June, Google announced plans to create a separate search index to crawl pages submitted in a sitemap, rather than just limit results from its overall index. Additional updates include synonym search, date biasing and top results biasing.
