Customize search results by overriding the SearchResults class
Development WebForms

You can customize Sitefinity's search results by using a customized SearchResults widget that inherits the SearchResults class. Then you can register the custom widget in the toolbox and use it on pages and page templates. 

For more information, see Register a new widget in Sitefinity CMS toolbox.

Following is a code sample that demonstrates a customized overridden SearchResults class. It filters the list of search results to display only results published in the last 10 days, by overriding the Search method:

using System;
using System.Collections.Generic;
using Telerik.Sitefinity.Abstractions;
using Telerik.Sitefinity.Services.Search;
using Telerik.Sitefinity.Services.Search.Data;
using Telerik.Sitefinity.Services.Search.Web.UI.Public;
namespace SitefinityWebApp
{
public class CustomSearchResults : SearchResults
{
protected override ISearchResultsBuilder GetSearcher()
{
return new MySearcher(this);
}
protected class MySearcher : ISearchResultsBuilder
{
public MySearcher(SearchResults control)
{
this.control = control;
}
public IEnumerable<IDocument> Search(string query, string catalogue, string[] searchFields, string[] highlightedFields, int skip, int take, out int hitCount)
{
return this.Search(query, catalogue, searchFields, highlightedFields, skip, take, out hitCount, false);
}
public IEnumerable<IDocument> Search(string query, string catalogue, string[] searchFields, string[] highlightedFields, int skip, int take, out int hitCount, bool setLinksOnlyFromCurrentSite)
{
var control = this.control;
var service = Telerik.Sitefinity.Services.ServiceBus.ResolveService<ISearchService>();
var queryBuilder = ObjectFactory.Resolve<IQueryBuilder>();
var searchQuery = queryBuilder.BuildQuery(query, control.SearchFields);
searchQuery.IndexName = catalogue;
searchQuery.Skip = skip;
searchQuery.Take = take;
searchQuery.OrderBy = null;
searchQuery.HighlightedFields = control.HighlightedFields;
// Contains the default filter - by current language
var currentFilter = searchQuery.Filter;
var myDatesFilter = new SearchFilter();
myDatesFilter.Operator = QueryOperator.And;
// Here we add a clause, that only results for the last 10 days will be displayed
myDatesFilter.AddClause(new SearchFilterClause("PublicationDate", DateTime.UtcNow.AddDays(-10), FilterOperator.Greater));
// Persist the language filter, if exists
if (currentFilter != null) myDatesFilter.AddFilter(currentFilter);
searchQuery.Filter = myDatesFilter;
IResultSet result = service.Search(searchQuery);
hitCount = result.HitCount;
return result.SetContentLinks();
}
protected readonly SearchResults control;
}
}
}
