When we launched On-Demand Indexing in Custom Search, our goal was to make it possible for you to include your new and changed pages quickly in your website’s search results. Since then, we’ve improved indexing freshness and doubled On-Demand indexing quotas. Today, we’re happy to announce further improvements to On-Demand Indexing that make the process simpler and more flexible.

First, we’re providing a new On-Demand Indexing API, which will allow you to initiate indexing actions programmatically. Your content management systems can trigger these new APIs when new content is being published, so that changes on your website are reflected automatically in Custom Search results.

Previously, you needed to provide validated Sitemaps in Webmaster Tools and then select a Sitemap for On-Demand Indexing in the Custom Search control panel. Now, to make this process simpler, you can submit Sitemaps directly within the Custom Search control panel. At this time, we will only consider URLs that belong to the same host serving the Sitemap and for sites verified by the owner of the Custom Search engine.

The best improvement: we now allow you to delete URLs from inclusion in your search. If a page on your site has been deleted, or has content that is inappropriate and you want to eliminate it from search results right away, you can list the URL in your sitemap and mark it for deletion by using an “expires” tag. For more information on this, and the new On-Demand Indexing API, please refer to our documentation. Based on the type of search engine you own, you have certain quotas for URL indexing and removal. You should be able to verify your quota usage in the control panel.

We hope that these changes make it easier for you to control the search experience for your users. As always, we look forward to your feedback.

Ever since the launch of Custom Search, users have asked us to provide more flexible options to integrate search into their websites. Today, we’re launching a set of new layout options for your Custom Search experience. If you go to the Look and feel tab, you’ll see a set of new layouts that you can choose from, as shown in the screenshot below.

The Two page and Results only layouts give you more flexibility than the Two column layout, which still requires the search box and results to reside on the same web page.

All of the above layouts are powered by the Custom Search Element. The new Google-hosted layout also embeds the Element on a Google-hosted page. This is because the Element offers greater flexibility and interactivity, font control, better customization using themes and style sheets, out-of-box metadata support for thumbnails and actions, support for client-side control over results presentation, and a superior mobile experience for smart phones and tablets.

There are a couple of additional reasons why all the new layouts use the Element (and we’ll continue to deliver new functionality this way too). We want all Custom Search users to be able to easily turn on upcoming new features on for their site visitors. Consolidating to the Element also allows us deliver features faster.

Along with these new layouts, we are also officially phasing out results presentation via the iframe. If you host results in an iframe today, you will see this option marked deprecated in the Look and Feel tab in the control panel. We encourage you to migrate as soon as possible to one of the Element-based layouts. We plan to replace iframe results soon to use embedded Elements. This will happen first with all existing Google-hosted results pages, which currently embed iframes.

So stay tuned -- there are exciting new features coming to Custom Search. And as always, we welcome your feedback.

Many of you have requested a simpler process for transferring Google Site Search ownership to a different user. For instance, you may have created, developed and customized your website's search experience under your Google account, but want the long-term management of the search engine to be performed by someone else. In the past, you would have been required to manually export the configuration, import it into a new Site Search instance and then cancel the old instance.

Now, you can very easily transfer the ownership of a Site Search engine to a new user by simply specifying a different Google account email address in the Business Settings tab in the control panel.

Once you’ve provided the appropriate account information for the new administrator account, the following things happen:

• A new Site Search engine is created with the identical configuration as your current Site Search engine.
• The new Site Search engine is owned and can be administered by the new account owner.
• Any unused query quota is transferred to the new Site Search engine.
• The new Site Search engine will show the transfer history in the Business settings in the control panel
• You can still continue to use the old engine, but ads may be displayed alongside search results and XML access is disabled.

Please note that either you or the new admin will also need to update the Search box code to represent the new Site Search engine ID. You can find this ID in the Basics tab in the control panel, marked “Search Engine unique ID”.

We hope this process makes it easier for you to transfer administration capabilities to the appropriate account owners in your organization. For more details, please refer to the articles on transferring ownership, and recommended post-transfer actions in the help center.

As always, we appreciate your feedback in the user forum.
