Windows Search Assistant
In Windows Internet Explorer 7, the legacy Windows Search Assistant is disabled by default. See Security and Compatibility in Internet Explorer 7 for additional information.
The Windows Search Assistant, located inside the Search bar, is a feature of Microsoft Internet Explorer 5 that provides a common query interface for users when starting a search. It helps refine the search process by providing a task-based approach. Also, it is not necessary for users to remember the various common and specialty search engines that are available.
The Search bar is an ideal substitution for using frames to display search results. Frames tend to consume 20 to 30 percent of the available screen space. There is no easy way for the frame to be dismissed to make room for the main content area. The Search bar is a more extensible solution as a navigation and user interface mechanism.

The Search Assistant was created to provide users with a single, unified search experience across different types of searches. The Search Assistant is a task-based search tool that allows users to specify what type of information they are looking for instead of what engine they want to use for their search.
Users generally use results pages from a variety of search engines. It's critical for users to be able to easily use the results of any search service. The Search bar provides the ability to store detailed information—such as text abstracts, URLs, or file size—in the ToolTips that appear when the mouse pointer hovers over a result. This helps keep the results page simple and provides detailed information when needed.
Because the Search bar and the Search Assistant appear to be an element of Windows Internet Explorer and not the Web page, the quality of the content loaded into the Search bar will directly affect the perceived quality of the browser. The Search Assistant was created to assist users in quickly finding information. To help accomplish these goals, the following UI requirements have been established to be included in the customization page for the Search Assistant. These requirements are very simple to support, and they allow for a personalized appearance.
Requirements for the Search Assistant UI include the following:
Pages need to work inside the Search bar.
The Search bar is a tight, constrained space that challenges even the best designers to fit everything inside. Make sure that your pages fit within the default size of the bar (200 pixels by 430 pixels) without any scrolling. If you require scrolling, make sure that a significant number of actual results (not category results) are immediately visible. All links to the search results should open in the main browser window. Try to avoid opening other pages in the bar as the Search bar does not have Back and Forward buttons.
Prioritize your UI.
Because the Search bar is a tight space, you will have to prioritize your UI. The basic rule is to provide the user with the best information without a lot of visual clutter or confusion. From the top of the page to the bottom, your UI should follow this order: your branding, search query fields to refine, the search results, and finally, your ads or other services. If you decide to use ads, try to keep them toward the bottom of the page. Never force users to scroll past your ads to see their results.
Use the Internet Explorer 5 features that help users find information.
Internet Explorer 5 offers a cartload of features that will make your results easier to use and enable you to convey more information to users without confusing them. These features include:
- Dynamic HTML. Dynamic HTML (DHTML) enables you to hide and display results and categories so that users can better browse the search results without having to return to the server for more information or lose the results they have already found. DHTML also enables you exact positioning on the page so that your results pages can maximize information.
- Hit highlighting. Hit highlighting is a simple object model call that automatically performs a Find operation on the destination page. Use hit highlighting so that users can quickly locate the first search result on a particular page.
- ToolTips. Internet Explorer 5 offers normal and rich text ToolTips to convey extra data when a user hovers the mouse cursor over an object. Use ToolTips on a search result to keep the search result list compact. ToolTips can provide information such as international language, object description, title, or URL.
To help illustrate these UI requirements, an example layout follows. As you can see, these results are convenient and easy to read.
The Search bar, which is designed with a very specific UI model, appears on the left of the screen and should always act as the navigation control for what appears in the main content area. By following the guidelines, you provide a user experience that's consistent with the Favorites, History, and Channels features. The Search bar is a display component of the browser, and is not an HTML frameset. When designing your content, always try to provide a list of available navigation targets in the Search bar and navigate the content in the main area appropriately.
To target the main window instead of the search pane with your hyperlinks, specify the possible value _main for the TARGET attribute in your A elements. The following is a sample anchor that targets the main pane.
<A HREF="http://www.microsoft.com" TARGET="_main">
The Search Assistant can be customized to meet the search needs of a company or individual. For example, additional information about search results can be stored within ToolTips, and search results can be highlighted on a particular Web page.
Building customized Search Guides to search Web pages for a word or phrase is easy in Internet Explorer 5. The new IShellUIHelper::NavigateAndFind method will load a specified Web page and scan the document for a match to the provided string. If a match is made, the string in the document is highlighted.
The following example will open the Microsoft Web site and search for Microsoft Corporation.
To help conserve available browser window space and to improve the readability of search results, Internet Explorer provides the ability to define what information about a given link should be contained in a ToolTip. By defining the TITLE attribute of an HTML anchor tag, Internet Explorer makes it possible to put abstract or supplemental information inside a ToolTip.
The following HTML sample makes the additional information in the ToolTip text possible when viewed with Internet Explorer.
<A HREF="http://www.acme-sports.com" TITLE="Latest sports news and scores, updated hourly. Interviews with winning players"> acme-sports - Latest sports news</A>
The ToolTip automatically breaks lines at 3 inches and can contain at least a paragraph of text. However, no more than 1,024 characters are allowed within the ToolTip text. You can also force a new line or tab spaces in the abstract by using the reserved characters and
for carriage return and line feed, and 	 for tab spaces. For example, when viewing the following HTML sample with Internet Explorer, a ToolTip with a carriage return and line feed after line 1 is displayed.
<A HREF="http://www.microsoft.com" TITLE="The text that will be displayed on line1 The text that will be displayed on line2 	The text that will be displayed on line3 	The text that will be displayed on line4"> Using multiple lines in ToolTips</A>
- Does your page fit within the 200-pixel by 430-pixel Search bar area without horizontal scrolling?
- Are all of your results from searches displayed in your bar?
- Are all of the search results set to target the main browser window?
- Does your UI enable users to refine their search?
- Does your UI follow the priority of elements?
- Does your design allow for some margin spacing around text and edges?
- Are your ads placed toward the bottom of the bar?
- Are you using hit highlighting to find the words that users searched for in the search results?
- Are you using ToolTips or another hide/show mechanism to convey metadata?
- Are you using DHTML in your bar?
- Are your results pages easy to use, especially for novice users?
- Does your code have an HTML comment in the HEAD of the document stating the page version and date generated?
The following questions are the top issues concerning authoring for the Search bar.
The Search Assistant gives users a task-based approach to finding information on the Web. They are no longer required to know the various common and specialty search engines that are available to them.
The Search bar is created using the same components used in the rest of Internet Explorer. Any functionality that is possible in Internet Explorer is possible in the Internet Explorer Search bar. This includes Microsoft JScript, Microsoft Visual Basic Scripting Edition (VBScript), Microsoft ActiveX Controls, DHTML, framesets, Cascading Style Sheets (CSS), and so on.
Frames solve only half the problem with searching. By using a frameset, the user is always forced to give up 20 to 30 percent of the available screen space. There is no way for the user to dismiss the frame and use its screen space for the main content area. Also, framesets have a host of navigation and usability problems when they are used as a general UI mechanism.
The Search bar provides a UI that the user controls. It gives users much more control over how their browser display space is used, because they can control whether the Search bar is visible.
