Hosted Site Search Services Reports

Google Custom (Free) and Site (Paid) Search Services

Google uses the tools they've created for the web search engine, and limits by domain name, host, and/or URLs. When someone enters a query in the search form on your site, the browser sends the form information to the Google server. Google looks for matching pages in the index, filters them to the pages on your site, sorts them by relevance, formats the results, and sends them back in an HTML page with links directly to the pages on your site. They use the buzzword "cloud" for this functionality.

Note: Different results, Google CSE vs.

A support document (cached copy) for the Google CSE and CSBE notes that some results may be different than those found in the same search on It attributes this to including more than three sites in the CSE, and says that the CSE is using a subset of the index.

They recommend limiting the CSE to three sites, changing the behavior to 'Search the entire web but emphasize included sites', or adding refinements that have the same effect.

As of August 16, 2007, the support note says "We're working to bring more complete results to all Custom Search Engines."

Custom Search

Load search results on the same page (CustomSearch AJAX API)

The new Custom Search Element is particularly good for blogs and wikis, where users can't upload any pages. However, configure or change it at all requires a knowledge of JavaScript and AJAX (for more information, see my Google CSE AJAX Decoded and CSE CSS pages).

Loading gcse object

Note: the AJAX API will only return 8 results per page and 8 pages for a total of 64 results. Clicking on the "More results" link will display the remainder of the results on a Google-hosted results page.
