There is a ContentValueSetValidator class:

var index = new LuceneIndex("SitemapIndex",
    CreateFileSystemLuceneDirectory("SitemapIndex"),
    new FieldDefinitionCollection(
        new FieldDefinition("updateDate", FieldDefinitionTypes.DateTime),
        new FieldDefinition("changeFrequency", FieldDefinitionTypes.Float)
    ),
    new StandardAnalyzer(Version.LUCENE_30),
    new ContentValueSetValidator(true, includeItemTypes:new string[]{ "BlogPost", "TextPage", "BlogOverview" }) );

ContentValueSetValidator has a second constructor with a parameter 'supportProtectedContent'. I don't have any further insights, since the code of this class is not self-explanatory:

https://github.com/umbraco/Umbraco-CMS/blob/v8/dev/src/Umbraco.Examine/ContentValueSetValidator.cs

Having this same issue. I already have the index the external one i need to just allow SupportProtectedContent and set it to true. Don't want to have to go through setting up the whole index again.

Hi Ismail

It looks like in the source for examine

https://github.com/Shazwazza/Examine/blob/864168c7f019908242dd56197e075edea5ee77cf/src/Examine/Providers/BaseIndexProvider.cs

that each index does have a ValueSetValidator property

and this can be set to be a new instance of a ContentValueSetValidator which takes a parameter to support protected content or not...

however as this property has it's 'set' protected, it can only be set via the constructor for the index, which you can only do when creating it afresh...

... but I might be misunderstanding! and there may be another way...

but looks like removing the existing index and creating a new one with the desired configuration is the way to go...

Currently it seems the Umbraco Examine Config package has some issues, which cause a boot error - at least while testing on Umbraco v8.12.2: https://github.com/callumbwhyte/umbraco-examine-config/issues

I implemented the following instead to enable SupportProtectedContent in ExternalIndex and close to the example documented here: https://our.umbraco.com/documentation/reference/searching/examine/indexing/#changing-ivaluesetvalidator

using Examine;
using Umbraco.Core;
using Umbraco.Core.Composing;
using Umbraco.Core.Scoping;
using Umbraco.Core.Services;
using Umbraco.Examine;
using Umbraco.Web.Search;

namespace My.Core.Composing
{
    public class CustomizeIndexComposer : IUserComposer
    {
        //[ComposeAfter(typeof(ExamineComposer))]
        public void Compose(Composition composition)
        {
            // replace the default IUmbracoIndexConfig definition
            composition.RegisterUnique<IUmbracoIndexConfig, CustomIndexConfig>();
        }
    }

    // inherit from the default
    public class CustomIndexConfig : UmbracoIndexConfig, IUmbracoIndexConfig
    {
        private readonly IPublicAccessService _publicAccessService;
        private readonly IScopeProvider _scopeProvider;

        public CustomIndexConfig(IPublicAccessService publicAccessService, IScopeProvider scopeProvider)
            : base(publicAccessService)
        {
            _publicAccessService = publicAccessService;
            _scopeProvider = scopeProvider;
        }

        // explicit implementation - overrides base class.
        IContentValueSetValidator IUmbracoIndexConfig.GetContentValueSetValidator()
        {
            bool supportProtectedContent = true;

            return new ContentValueSetValidator(false, supportProtectedContent, _publicAccessService, _scopeProvider);
        }

        // explicit implementation - overrides base class
        IValueSetValidator IUmbracoIndexConfig.GetMemberValueSetValidator()
        {
            var excludeFields = Umbraco.Core.Constants.Conventions.Member.GetStandardPropertyTypeStubs().Keys;

            // include everything except the above
            return new MemberValueSetValidator(null, null, null, excludeFields);
        }

        // explicit implementation - overrides base class.
        IContentValueSetValidator IUmbracoIndexConfig.GetPublishedContentValueSetValidator()
        {
            bool supportProtectedContent = true;

            return new ContentValueSetValidator(true, supportProtectedContent, _publicAccessService, _scopeProvider);
        }
    }
}

is working on a reply...
