    Support for Internet Explorer 10.

  • By default, Internet Explorer 9 is often configured to use the Compatibility View mode that displays web pages as if you were using an earlier version of IE and therefore, does not support newer CSS styles. You can disable the IE 9 compatibility View mode (see the Microsoft document How to use Compatibility View in Internet Explorer 9).

  • You will get the best Coveo user interface experience with the latest version of your browsers. More recent Cascading Style Sheet (CSS) styles may not be rendered by older browser versions.

    Example: When you use Internet Explorer 9 in Compatibility View mode, the rounded corners and shadings of facets are not rendered.

  • Coveo search interfaces no longer support Internet Explorer 7 and 8 since Microsoft stops supporting those versions (see Support for Older Versions of Internet Explorer Ended).

  • The Coveo .NET search interfaces display a warning message when the connection is established using Internet Explorer 6 (IE6) that is not supported.

Tip: You can use the browser built-in search box as an access point to your Coveo search interface (see Coveo Search From a Browser Built-in Search Box).

The Coveo Platform also supports mobile browsers (see Mobile Access Points).

Note: The Coveo JavaScript Search Framework browser support may be a bit different (see Browser Support).
