2. Waar komen we vandaan?

3. Item buckets Niet zichtbaar (standaard)
Theoretisch ongelimiteerd aantal subitems
Geen parent child relatie

4. Handig om te weten
<setting name="BucketConfiguration.BucketFolderPath" value=„yyyy\/MM\/dd\/HH\/mm”/>
<field fieldName="group" storageType="YES" indexType="TOKENIZED"    vectorType="NO" boost="1f" type="System.GUID" settingType="Sitecore.ContentSearch.LuceneProvider.LuceneSearchFieldConfiguration, Sitecore.ContentSearch.LuceneProvider”>

6. Facet Search

8. Linq to Sitecore = gold All Any
Between — with an extra overload for including or excluding the start and end ranges.
Boost — makes this part of the query more important than the other parts.
Cast — you can use this instead of Select.
Contains

Facets — an extension that fetches the facets of predicates.
First

Match — an extension for running regular expression queries.
OrderBy

9. Facet implementatie
public static IQueryable<Facet> GetFacets(IQueryable<Product> query, string[] facets)
        {
            var facetGroups = new List<Facet>();
            query = facets.Aggregate(query, (current, facetName) => current.FacetOn(c => c[facetName]));
            FacetResults facetResults = query.GetFacets();
            foreach (FacetCategory category in facetResults.Categories)
            {
                var group = new Facet(key, friendlyName);
                foreach (Sitecore.ContentSearch.Linq.FacetValue facetValue in category.Values)
                {
                    group.Values.Add(new Models.FacetValue(facetValue.Name, facetValue.Aggregate));
                }
                facetGroups.Add(group);
            }
            return facetGroups.AsQueryable();
        }

using (var context = ContentSearchManager.GetIndex("sitecore_master_index").CreateSearchContext()) {
var results = context.GetQueryable<Product>().Where(prod => prod.Content.Contains("search box text").FacetOn(f => f.Color).FacetOn(f => f.Gender)).GetResults();
int totalHits = results.TotalHits; var searchResuls = results.Hits; var facets = results.Facets; }

12. namespace Sitecore.ContentSearch.Linq{
    public static class QueryableExtensions

        public static IQueryable<TSource> FacetOn<TSource, TKey>(this IQueryable<TSource> source, Expression<Func<TSource, TKey>> keySelector);

        public static IQueryable<TSource> FacetOn<TSource, TKey>(this IQueryable<TSource> source, Expression<Func<TSource, TKey>> keySelector, int minimumResultCount, IEnumerable<object> filterValues);
        public static IQueryable<TSource> FacetPivotOn<TSource>(this IQueryable<TSource> source, Expression<Func<FacetPivotQuery<TSource>, FacetPivotQuery<TSource>>> keySelector);

        public static IQueryable<TSource> Page<TSource>(this IQueryable<TSource> source, int page, int pageSize);
    } }

13. Linq voorbeeld resultsQuery = resultsQuery.Where(item =>
                    item.Path.StartsWith("/sitecore/content/sites/autohouse")
                    && !item.ExcludeFromSearchResults
                    && (item.TemplateName == ContentPage.TEMPLATE_NAME
                    || item.TemplateName == NewsDetailPage.TEMPLATE_NAME
                    || (item.TemplateName == MasterProductPage.TEMPLATE_NAME
                            && item.brand.Equals("Brand X")
                            && (item.useforsupport.Equals("1") || item.useforconsumerassortment.Equals("1")))
                    || (item.TemplateName == ColorProductPage.TEMPLATE_NAME
                    )
                    && item.Language.StartsWith(lang)).OrderByDescending(x => x.itemno);
