Need to create a search page

Vote:

public class DefaultPageViewModel<T> : IPageViewModel<T> where T : PageData
{
public DefaultPageViewModel(T currentPage)

{
CurrentPage = currentPage;
Section = ContentExtensions.GetSection(currentPage.ContentLink);
}
public T CurrentPage { get; set; }
public IContent Section { get; set; }
}


What to keep in the place of 'T' ?

showing error on 
DefaultPageViewModel<T> ->(CS0311) The type 'T' cannot be used as type parameter 'T' there is no implicit reference converse to 'T' to 'EPiServerDemo.Models.Pages.SitePageData'

IPageViewModel<T> -> (CS0535) DefaultPageViewModel<T> does not implement interface member of 'IPageViewModel<T>.Layout' .

Please help me fix this error.

This looks like it's a base viewmodel for any of the view models in your site.It also looks like maybe IPageViewModel<T> has a restriction to SitePageData which is likely your base page model with base properties. So you'll want change this class (DefaultPageViewModel<T>) from PageData to SitePageData

Then if you're createing a search page I'd expect the following

SearchPage Model inheriting SitePageData
SearchPageController passing in SitePageData in the Controller method
SearchPageViewModel inhertiing DefaultPageViewModel<T> passing SearchPage as the T param
SearchPage View passing in the SearchPageViewModel

This should all work. Just make sure you're interface and classes generic parameter type restrictions match.

Also as a point on design, your ViewModel should not be setting properties such as

CurrentPage = currentPage;
Section = ContentExtensions.GetSection(currentPage.ContentLink);

The viewmodel should be kept clean, those properties should be setup by the controller or ideally a factory/service for your ViewModel generation.

Is it necessary to create a search page in regards to implementing Episerver Find features.?

Scott Reed - Sep 02, 2021 12:47

Search & Navigation (Formally Find) is just a search platform based on elastic that indexes pages, blocks, media and any IContent. The .NET API is just a code API and can be called anywhere you like. This could be a search page if you're creating a search page or it could be in a header for a quick search, a block or anywhere really where you're searching/surfacing large groups of content.

While implementing Find, what are things we have to create to include the following features:
Highlighting Search Keyword
Highlighting Best Bets
Handling Stemming
