Coming to Microsoft Ignite next week? Then I invite you to come see Kristopher Loranger and I present on Tuesday, May 5:
Effective Search Deployment and Operations in SharePoint Server 2013
We'll be covering some architecture best practices, detailed look at query flows and the indexer. Most of the focus will be OnPrem SP2013, but we expect the concepts to cross-over to SP2016 as well.
Looking forward to presenting again in such a big forum!
