Goal

The aim of this article is to demonstrate how to index DateTime fields so that their type is properly parsed passed to the Hawksearch API.

...

Navigate to Administration → Search indexes (your-site-domain/Sitefinity/Administration/Search)
Open the index for editing
Under Advanced → Additional fields for indexing add the fields e.g. LastmodifiedPublishedDate, DateCreatedReleasedDate
Save the changes

Add the fields to a Content item

In order for these fields to be indexed you also need to add them as a custom fields to a e.g. News item

Create a News item
On the top right side click on the Settings icon and select the Custom Fields
Add a custom field of type Date and Time and with the name you have added in the Advanced settings of the Index e.g. PublishedDate
Press Continue and Done
Save Changes

...

Create configuration

In order to alter the type of particular fields we need to store them in a configuration and then use that configuration in a custom search service. Below you will find the ready to use configuration:

...

Code Block

language	c#

using System;
using SitefinityWebApp;
using Telerik.Sitefinity.Abstractions;
using Telerik.Sitefinity.Configuration;

namespace Hawksearch122
{
    public class Global : System.Web.HttpApplication
    {
        protected void Application_Start(object sender, EventArgs e)
        {
            Bootstrapper.Bootstrapped += Bootstrapper_Bootstrapped;
        }

        private void Bootstrapper_Bootstrapped(object sender, EventArgs e)
        {
            Config.RegisterSection<DatetimeFieldsConfig>();
        }
    }
}

Infonote

Add your custom fields to Sitefinity Settings

After you have registered the configuration navigate to Advanced settings → DatetimeField section and add :

Navigate to Administration → Settings → Advanced → DateTimeFields (your-site-domain/Sitefinity/Administration/Settings/Advanced)
Add the DateTime fields you wish to alter e.g. PublishedDate

...

Info

Setup search service

In order to

alter

modify all the

type to be properly mapped you need to modify all DateTime fields to have the proper type

DateTime fields to the index you need to create a custom search service which inherits the HawkseachService class and overrides the CreateIndex , which also implement the ModifyDatetimeFields method . Please refer to the code snippet below

:

.

Code Block

language	c#

using System;
using System.Collections.Generic;
using System.Linq;
using Hawksearch.Search;
using Telerik.Sitefinity.Configuration;
using Telerik.Sitefinity.Services.Search;

namespace SitefinityWebApp
{
    public class CustomSearchService : HawksearchService
    {
        public override void CreateIndex(string sitefinityIndexName, IEnumerable<IFieldDefinition> fieldDefinitions)
        {
            var definitionList = new List<IFieldDefinition>(fieldDefinitions);

            this.ModifyDatetimeFields(definitionList);

            base.CreateIndex(sitefinityIndexName, definitionList);
        }

        private void ModifyDatetimeFields(List<IFieldDefinition> definitionList)
        {
            var configManager = ConfigManager.GetManager();
            var section = configManager.GetSection<DatetimeFieldsConfig>();

            if (section != null)
            {
                var dateTimeFields = section.DatetimeFields.Keys;

                foreach (var field in dateTimeFields)
                {
                    var dateTimeField = definitionList.FirstOrDefault(f => f.Name == field);

                    if (dateTimeField != null)
                    {
                        definitionList.Remove(dateTimeField);

                        var dateTimeFieldDefinition = Telerik.Sitefinity.Abstractions.ObjectFactory.Resolve<IFieldDefinition>();
                        dateTimeFieldDefinition.Name = "Datetime"dateTimeField.Name;
                        dateTimeFieldDefinition.Type = typeof(DateTime);

                        definitionList.Add(dateTimeFieldDefinition);
                    }
                }
            }
        }
    }
}

Note
Once you implement the code in Visual Studio , build your solution and you will also have to reindex the index you are using from Administrator → Search Indexes → Action → Reindex

Register custom search service

In order to use you custom search service instead of the built-in one please refer to this documentation:
Register custom search service

Info

Check field type in Hawksearch

After you have indexed please open your Hawksearch dashboard and check the type of the field you have created.

You can find them under Workbench → Data Configuration → Fields

It should look like this :
