Item buckets

• Niet zichtbaar (standaard)

• Theoretisch ongelimiteerd aantal subitems

• Geen parent child relatie

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”>

Facet SearchFacet Search

Coveo

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 • Count • ElementAt • EndsWith • Equal • Facets — an extension that fetches the

facets of predicates. • First • FirstOrDefault • Last • LastOrDefault

• Min • Max • Match — an extension for running regular

expression queries. • OrderBy • OrderByDescending • Select • Single • SingleOrDefault • Skip • Reverse • Take • ToList() • ToLookUp() • ToDictionary() • Page — an extension that does Skip and

Take automatically for you. • StartsWith • Union

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(); }
