In general, Google Site Search searches across a set of sites you specify. You cannot configure Google Site Search to search the entire web; in consequence, your results are unlikely to match those returned by Google Web Search, for several reasons:
- Google Site Search is designed to include return results only from specified sites.
- Google Site Search doesn’t include Google Web Search features such as Oneboxes, real-time results, universal search, social feaures, or personalized results.
- Using Google Site Search won't affect a page's inclusion or ranking in the Google index. The new Google Site Search index is designed to improve the results for Google Site Search sites. Any additional pages in the Google Site Search index aren't included in Google's index and won't impact a site's behavior in the Google search results.
- If your Google Site Search includes more than ten sites, the results may be from a subset of our index and may differ from the results of a 'site:' search on Google.com.
If you’d like to see more complete results in Google Site Search, check the following:
- Make sure you've added the page you expect to see with no spelling errors or URL-pattern errors.
- On the Sites page, make sure to include no more than ten sites in the Included sites section. Each domain you add is counted towards this total; pages within these domains are not.
- If there are specific pages that aren't appearing in your Site Search results, submit the URLs for on-demand indexing.
- Leave your search engine configuration intact—with no changes to the included or excluded sites—for approximately 20 days. Users have reported that this can improve the coverage for search engines that include more than 10 domains.
