About Facets

Facets are convenient user interface controls allowing you to easily filter or refine search results according to specific criteria. A facet presents a list of the items found in the current search results and indicates the number of occurrences for each item, helping you to quickly grasp and refine the search results.

You can use one facet or a combination of facets to refine your search (see Refining Search Results Using Facets). The facet items are typically sorted either from the most frequent to the least frequent or alphanumerically, ascending or descending.

Facets can also include calculated values (see Computed Facets) and numerical values (see Numerical Range Facets).

Each search interface comes with its set of tailored facets that appear on the side of the search results page.

Example: In the following figure, the Type facet lists the different file types found in the search results. You can see that the Web Page format is the most frequent type of found documents, but because PDF is selected, search results are refined to only show PDF documents.

Facet name
Facet items – Click an item or its check box to narrow search result to this item.
A search box appears when the list of available items is long – Type a few characters to easily find and select additional items.
Eraser icon – Click to clear all active filters.
Show/Hide icons – Click to respectively show facet items or hide inactive facet items.
Exclude icon – Click to exclude results corresponding to this item.
Extend/Reduce control (More, Fewer) – Click More to extend or Fewer to reduce the list of visible items.
Note: Use the latest version of supported browsers to get the best facet experience. When you use Internet Explorer 7, 8, or 9 in Compatibility View mode, the rounded corners and shadings of facets are not rendered.

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).

Note: Your Coveo administrator can add, remove, or configure built-in or custom facets according to your needs in a .NET search interface (see Adding or Customizing a Facet With the .NET Interface Editor) or in a JavaScript search interface (see JavaScript Search Interface Editor or Making Basic JavaScript Search Page Customization With the Legacy Interface Editor).

Your Coveo administrator can also configure facets to appear on either side of the .NET search results page (see Configuring the Position of Facets and Related Results Panels With the .NET Interface Editor). The Search In facet automatically appears when your Coveo administrator defines one or more custom .NET search scopes (see Configuring a Custom Scope With the .NET Interface Editor).
