All content pages inherit the Search composition. From the beginning, the composition had Search keywords. We created the whole website and keywords exist in the index. Now we need to add new properties to the composition ("topRated" and "hideFromSearch") but those properties don't exist in the index so the index doesn't return the result.

My index query:

var criteria = searcher.CreateQuery(defaultOperation: BooleanOperation.And);

        var query = criteria
            .GroupedOr(new[]
            {
                Constants.Indexes.HideFromSearch.ToCultureSearchField(culture),
                Constants.Indexes.HideFromSearch
            }, "0")
            .AndNot(x => x.Field(ExamineFieldNames.CategoryFieldName, IndexTypes.Media));
            .GroupedOr(new string[] { Constants.Media.TopRatedProperty, Constants.Media.TopRatedProperty.ToCultureSearchField(culture) }, "1")

I tried to write some code to republish all pages but it doesn't work:

public string UpdateContent(int? homePageId, string culture = "de-AT")
    {
        if (!homePageId.HasValue)
        {
            return "Home Page is required!";
        }

        var cache = _context.GetRequiredUmbracoContext();
        if (cache?.Content == null)
        {
            return "Can't resolve the Umbraco context.";
        }

        RePublishPages(homePageId.Value, culture, cache);

        return "Ok";
    }

    private void RePublishPages(int parentId, string culture, IUmbracoContext umbracoContext)
    {
        if (umbracoContext?.Content is null)
        {
            return;
        }

        var page = umbracoContext.Content
            .GetById(parentId);

        if (page is null)
        {
            return;
        }

        if (page.Children.Any())
        {
            foreach (var child in page.Children)
            {
                RePublishPages(child.Id, culture, umbracoContext);
            }
        }

        var content = _contentService.GetById(page.Id);
        if (content is not null && content.Published && content.PublishedCultures.Any(x => x.Equals(culture, StringComparison.OrdinalIgnoreCase)))
        {
            _contentService.SaveAndPublish(content, culture);
        }
    }

EDIT: Rebuild index doesn't fix the problem
