Enterprise Search @Belarus SharePoint User Group

Yesterday I spoke at Belarus SharePoint User Group and presented brief overview how we built our in-house Global Search solution as well as few other relevant topics. Such as a summary of available options to connect external content to SharePoint search, including our EPAM Data Import Framework, which in several aspects outcomes SharePoint BCS model.

The killer point of yesterday discussion was  presentation of my finding regarding relevancy calculation in new SharePoint 2013 search. As far as I’m concerned (and briefly described in previous Explain Rank post, SharePoint uses neural network to calculate final score, and as a part of calculation process it uses hyperbolic tangent 🙂 Which kind of scared everybody, but at least now everybody knows that SharePoint relevancy is not a piece of cake.
