After a query is executed against the index, the browser is redirected automatically to the Search Results page. The results page can potentially contain the following types of results:
High confidence results
Keyword and Best Bet results
The layout of the information on the results page is a direct result of combining the search Web Parts for the results page. Because the results are passed from the index to the search results page in XML format, many of these Web Parts use XSLT to format the results. This is why you’ll need to enter additional XSLT commands if you want to perform certain actions, such as adding another property to the Advanced Search drop-down list.
