Crawl content (Office SharePoint Server 2007 for Search)

  • Artikel

Typically, you will want to schedule most crawls, but there are times when you might want to manually start a crawl. For example, you might start a crawl to apply administrative changes such as crawl rules to the content you crawl and index, or to determine if an error in the crawl log has been resolved. Moreover, whether a crawl is started by a schedule or manually, you might need to stop or pause one or more crawls. For example, an administrator whose server hosts the content you are crawling might notify you that crawling is placing too much load on the server or you might be alerted that the server you are crawling is currently offline. In either of these cases, you might want to stop or pause the crawl.

Consider that more time and server resources are required to perform a full crawl than are required to perform an incremental crawl. Full crawls:

  • Consume more memory and CPU cycles on the index server than incremental crawls.

  • Consume more memory and CPU cycles on the front end-Web servers when crawling content in your server farm. This does not apply to content that is external to your server farm.

  • Use more network bandwidth than incremental crawls.

Wichtig

When you stop a crawl of any content source, the next time you crawl that content source, Microsoft Office SharePoint Server 2007 for Search automatically performs a full crawl of the content source the next time it is crawled. This is true even if you attempt to perform an incremental crawl. Therefore, carefully consider whether you should pause the crawl instead of stopping the crawl.

Nonetheless, you must also be careful not to pause crawls for too many content sources at the same time, because each content source that is paused consumes memory and CPU resources on the index server.

To start a full or incremental crawl, stop, pause, or resume a crawl, perform one of the following procedures:
