Sitecore ContentSearch

The NuGet package meant for Sitecore contains the below config file as well, to add the Danish analyzer to the culture execution contexts for the Danish culture da.

With this the Danish analyzer will be used when indexing items in language da and create better terms that should result in better search results.

<configuration xmlns:patch="http://www.sitecore.net/xmlconfig/"> <sitecore> <contentSearch> <indexConfigurations> <defaultLuceneIndexConfiguration> <analyzer> <param> <map>  <mapEntry patch:before="*[1]" type="Sitecore.ContentSearch.LuceneProvider.Analyzers.PerExecutionContextAnalyzerMapEntry, Sitecore.ContentSearch.LuceneProvider"> <param hint="executionContext" type="Sitecore.ContentSearch.CultureExecutionContext, Sitecore.ContentSearch"> <param hint="cultureInfo" type="System.Globalization.CultureInfo, mscorlib"> <param hint="name">da</param> </param> </param> <param hint="analyzer" type="Sitecore.ContentSearch.LuceneProvider.Analyzers.DefaultPerFieldAnalyzer, Sitecore.ContentSearch.LuceneProvider"> <param hint="defaultAnalyzer" type="Additio.Lucene.Analyzers.DanishAnalyzer, Additio.Lucene.Analyzers"> <param hint="version">Lucene_30</param> </param> </param> </mapEntry> </map> </param> </analyzer> </defaultLuceneIndexConfiguration> </indexConfigurations> </contentSearch> </sitecore> </configuration>

Remember to also use the CultureExecutionContext when searching so your query get analyzed the same way as when the item's fields were indexed.

using (var context = ContentSearchManager.GetIndex("INDEX_NAME").CreateSearchContext()) { var cultureExecutionContext = new CultureExecutionContext(new CultureInfo("da")); var query = context.GetQueryable<SearchResultItem>(cultureExecutionContext); // configure query and get results }
