Step 1: Go to the management center, Click Manage applications, click Search Service applications to go to the search management configuration page, and select the content source
Step 2: Click Create content source, name the content source, select a website in the crawler content type, and select only the first page of each start address in the crawler settings, in this step, you need to pay attention to the selection of network crawling settings. If you select custom, the larger the server distance from the configuration, the whole network may be crawled, causing your server resources to be exhausted dramatically.
Step 3: Enable incremental crawling at the crawling plan point to create an incremental crawling plan. Note that full crawling will re-crawl all content sources. incremental crawling only accesses the content updated after the previous crawling. Even if you select incremental crawling, the newly created content source performs a full crawling operation first. Full crawling is much more resource-consuming than incremental crawling, so try to use incremental crawling instead of full crawling. the incremental crawling plan can be set relatively short to keep the content of search results fresh.
Step 4: You can manually start incremental crawling and full crawling, or wait for the automatic execution of the crawling plan
Step 5: View search results
