Today, we announced Google Site Search, a hosted website search product that takes advantage of the Custom Search platform to offer high quality search to any website. Google Site Search integrates features that offer site visitors a search experience closer to what they're used to on Google.com. Here are a few of the new features:
- Expanded coverage: We already search through all of your pages that are in the Google.com index. Tell us about more pages on your site by submitting a Sitemap. We'll crawl your Sitemap and add these pages to your custom search engine so that your search engine has the maximum coverage. (These additional pages will only be available to your custom search engine; your PageRank and Google.com rankings won't change in any way.)
- Custom Synonyms: You can now define custom synonyms for your custom search engine. For example, you can define "cd" as meaning"certificate of deposit." When a visitor searches for "cd" on your search engine, we will return pages that contain either "cd" or "certificate of deposit." You can specify these synonyms in the XML definition of your search engine.
- Date Biasing: Fine-tune the relevance of search results by specifying a bias for newer documents. We allow various levels of biasing, the highest of which approximately sorts by date.
- Top Results Biasing: If you want the first N results to always match a refinement, you can specify that as a property of the refinement. We will try to fill up the top N positions with results matching that refinement before showing other relevant results.
