In some situations, you might want to restrict a web search, news search, or blog search to a specific site or blog. When you apply restrictions like this, you would typically also want to set your own custom label on the associated section of search results, and you might want to style this section of results differently.

<style type="text/css">
/* customize checkbox for -siteSearch section and
 * set section title and keep label to bold
 */
.gsc-resultsRoot-siteSearch .gsc-keeper {
  background-image : url('../../css/orange_check.gif');
  font-weight : bold;
}
.gsc-resultsRoot-siteSearch .gsc-title { font-weight : bold; }
...

// site restricted web search with custom label
// and class suffix
var siteSearch = new google.search.WebSearch();
siteSearch.setUserDefinedLabel("Amazon.com");
siteSearch.setUserDefinedClassSuffix("siteSearch");
siteSearch.setSiteRestriction("amazon.com");
searchControl.addSearcher(siteSearch);

// site restricted web search using a custom search engine
siteSearch = new google.search.WebSearch();
siteSearch.setUserDefinedLabel("Product Reviews");
siteSearch.setSiteRestriction("000455696194071821846:reviews");
searchControl.addSearcher(siteSearch);

Controlling Expansion Mode

kamagra ohne rezept kamagra kamagra verkaufe gut preis kamagra on line kamagra online mit mastercard viagra mejor precio viagra comprar viagra viagra descuentos viagra barato
The following example demonstrates the use of a search control in which each searcher is operating in a different expansion mode. Note that if the searcher is being drawn in tabbed mode, expansion mode is ignored. In that case, the searcher always operates in open mode.

// local search, partial
options = new google.search.SearcherOptions();
options.setExpandMode(google.search.SearchControl.EXPAND_MODE_PARTIAL);
searchControl.addSearcher(new google.search.LocalSearch(), options);

// web search, open
options = new google.search.SearcherOptions();
options.setExpandMode(google.search.SearchControl.EXPAND_MODE_OPEN);
searchControl.addSearcher(new google.search.WebSearch(), options);

// web search, open, alternate root
var options = new google.search.SearcherOptions();
options.setExpandMode(google.search.SearchControl.EXPAND_MODE_OPEN);
options.setRoot(document.getElementById("somewhere_else"));
searchControl.addSearcher(new google.search.WebSearch(), options);

In some applications, it is desirable to project search results for a given service into an arbitrary location on the web page. This mode of operation is supported by using the setRoot() method of the service's corresponding searcher object.

Searcher Objects

The addSearcher() method of the search control object determines which search services the search control operates. This method takes two arguments, one which specifies the service object, and a second argument specifying options for the service. The following searcher objects (services) are currently supported:

    * google.search.LocalSearch
    * google.search.WebSearch
    * google.search.VideoSearch
    * google.search.BlogSearch
    * google.search.NewsSearch
    * google.search.ImageSearch
    * google.search.BookSearch (experimental)
    * google.search.PatentSearch

Given that the Google AJAX Search API is a work in progress, the list of supported services will evolve over time.

Google AJAX API Loader

Use the google.search.* namespace for all classes, methods and properties you currently use in the Google AJAX Search API, replacing the G prefix with this namespace. For example, the GSearchControl object is mapped to google.search.SearchControl when using the Google AJAX API loader:
