You can create a search solution to help website visitors find what they want by combining Optimizely Data Source controls, listing controls and even third-party controls (.NET etc). If you require more extensive search functionality in your website solution, you can integrate third-party search engines with Optimizely.
Searching for a page
The Optimizely CMS SearchDataSource web control is a flexible web control which supports property searches, and you can apply different criteria to the search functionality.
Searching for pages often occurs through a Property-based search which 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 Optimizely SearchDataSource web control supports this type of search.
From code-behind files, you also can call the FindPagesWithCriteria() method of the EPiServer.DataFactory class to perform property-based searches. The FindPagesWithCriteria method is used by the SearchDataSource control when you perform a property-based search.
From markup or visual design mode, 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 FindPagesWithCriteria. You must add the SearchDataSource control's DataSourceID attribute to the control that renders the data.
A filter is a general mechanism in Optimizely that is used to manage and manipulate information in listings and collections of content (PageDataCollection, IContent). As a developer, you can construct your own filters to use in conjunction with listings to display content. A filter is used for adding, removing, and sorting.
The following most common built-in filter options are as follows:
- SortBy and SortDirection used to specify a custom property to sort on.
- SortOrder uses a predefined sorting from FilterSortOrder enum.
- MaxCount and SkipCount to limit number of items.
- EnableVisibleInMenu, PageTypeID, and so on.
- LanguageBranches collection to limit the search.
- Criteria collection constrains the search result (used for property-search or as filters).
- SelectParameters collection to set attribute values from other sources (Control, Cookie, Form, Profile, QueryString, Session, EPiServer Property).
- FilterForVisitor works with IEnumerable<IContent> and PageDataCollection.
The Optimizely filter classes and enumerations are documented in the EPiServer.Filters namespace. You can create your own filters by extending the EPiServer.Filters.IPageFilter class.
