This article provides a basic introduction to searching and filtering in EPiServer CMS. A search solution to help website visitors find what they want can be created by combining EPiServer Data Source controls, listing controls and even third party controls (.NET etc). If you require more extensive search functionality in your website solution there are also third party search engines that can be integrated with EPiServer.

The EPiServer CMS SearchDataSource is one of the major data source controls shipped with EPiServer CMS it is a flexible web control enabling different types of searches in an EPiServer CMS website, see below for further information.

Page Search

The SearchDataSource web control can support text and property searches; also different criteria can be applied to both types of searches.

Searching for pages often comes in two distinct forms:


Text based searches usually allow the user to input one or more keywords; any pages that contain those words should be returned and presented to the user.


A property based search provides an efficient and powerful tool to retrieve pages based on any property values, typically of types other than string. From markup (or the visual design mode in Visual Studio), the EPiServer SearchDataSource web control can support both types of searches; also different criteria can be applied to both types of searches. From code-behind files, you can also call the FindPagesWithCriteria() method of the EPiServer.DataFactory class to perform property based searches. The FindPagesWithCriteria method is used by the SearchDataSource control when performing a property based search.

From markup add PropertyCriteria controls to the SearchDataSource tag. From code-behind files, create EPiServer.PropertyCriteria instances and insert them into a PropertyCriteriaCollection that is passed to the FindPagesWithCriteria method. You are required to add the SearchDataSource control's DataSourceID attribute to the control that renders the data.

File Search

In order to search for file content and file information the SearchFiles attribute must be set to true in the SearchDataControl.

Sorting and Filtering

A filter is a general mechanism in EPiServer that is used to manage and manipulate information in listings and collections of pages (PageDataCollection). As a developer, you can construct your own filters, which can then be used in conjunction with listings to display content. A filter has three primary functions and is used for adding, removing and sorting.

See the most common built-in filter options below:

The EPiServer filter classes and enumerations are documented in EPiServer.Filters namespace.

It is also possible to create your own filters by extending the EPiServer.Filters.IPageFilter class.
