Contents
In SharePoint, content is automatically crawled based on a defined crawl schedule. The crawler picks up content that has changed since the last crawl and updates the index. You will want to manually request crawling and full re-indexing of a site, a document library, or a list after a schema change has occurred.

What is the definition of a continuous crawl?
A single continuous crawl includes all content sources in a Search service application for which continuous crawls are enabled. Similarly, the continuous crawl interval applies to all content sources in the Search service application for which continuous crawls are enabled.
Continuous crawls help ensure freshness of search results because the search index is kept up to date as the SharePoint Server content is crawled so frequently. Thus, continuous crawls are especially useful for crawling SharePoint Server content that is quickly changing.
What happens during a full search engine crawl?
During a full crawl, the search engine crawls, processes and indexes every item in the content source, regardless of the previous crawl status. In most cases, we do not need to (re-)index everything in the content source.
What’s the difference between a full and an incremental crawl?
Full Crawl. During a full crawl, the search engine crawls, processes and indexes every item in the content source, regardless of the previous crawl status. Incremental Crawl. In most cases, we do not need to (re-)index everything in the content source.
