Scale enterprise search in SharePoint Server

APPLIES TO: 2013 2016 2019 Subscription Edition SharePoint in Microsoft 365

Sometimes it's necessary to scale your search topology, for example:

• Because your search environment has grown in amount of content or number of users, or both.

• Because you've identified a bottleneck while monitoring your search solution and this bottleneck might affect the search performance.

• Because your search environment has specific performance requirements that weren't addressed when you implemented one of the recommended search architectures described in Plan enterprise search architecture.

1. Redesign your search topology:

• If you're scaling because your search environment has grown, follow the guidance in Redesign enterprise search topology for more content and users in SharePoint 2016.

• If you're scaling because you have specific performance requirements or to remove a bottleneck, follow the guidance in Redesign enterprise search topology for specific performance requirements in SharePoint 2016.

2. Implement the redesigned topology either on new servers, servers in your existing farm, or a combination. Follow the guidance in Manage the search topology in SharePoint Server.
