This article describes the new crawl type “Continuous Crawls” in SharePoint 2013.

Continuous Crawl in SharePoint 2013

In SharePoint 2010 there were two crawl types, “Full Crawl” and “Incremental Crawl”, whereas in SharePoint 2013 they have introduced a new crawl type named “Continuous Crawls” that keeps the content up to date. Continuous crawls are enabled only for the Content Sources that use the “SharePoint Sites” content source type. If a full crawl or incremental crawl is running then you will not be able to start a new crawl for the same content source until the old crawl is completed whereas multiple continuous crawls can run at the same time. All contents will be up to date because of continuous crawl.
