We all remember the pain involved in switching Search Providers from Lucene to Solr.  There were many a tales of woe.  It crushed dreams.  Drinks were had in order to lament. Maybe it wasn’t that bad.  But… Sitecore listened to us!

With Sitecore 9, switching search providers is EASY.  How easy? Check out the setting in your web.config:

Is it really that easy? In a word, “yep”.  Prying open the other search-related configs, we can see some familiar SC9 markup. Here’s the top portion of the Sitecore.ContentSearch.Lucene.DefaultIndexConfiguration.config file:

Notice the search:require attribute.  That tells Sitecore to only execute that when the search is defined as Lucene. Opening up the corresponding Solr config file (Sitecore.ContentSearch.Solr.DefaultIndexConfiguration.config):

Long gone are the “An index with the name ‘sitecore_marketing_assets’ already exists” because you forgot to nuke the Lucene index definition config when you swapped to Solr.


This entry is part of my series "Nine on Nine" which is a "quick peek" at nine new things in Sitecore 9.  I've been messing a bit with the Technical Preview, and there's lots of exciting stuff to share.  Some of these might change a little in regards to General Availability, but hopefully not too much... These posts won't cover everything in depth, as I hope to do more detailed analysis in the coming months. Other Entries in Nine on Nine
