In SP2010, we have two types of crawls; Full or Incremental Crawl. In a nutshell, your search index can be made on-average fresher, but it is not real-time. Right now we do Full Crawls weekly and incremental crawls hourly.<\/p>\n
One of the limitations of Full and Incremental Crawls in SP2010 is that they cannot run in parallel, i.e. if a full or incremental crawl is in progress, the admin cannot kick-off another crawl on that content source. This forces a first-in-first-out approach to how items are indexed.<\/p>\n
Moreover, some types of changes result in extended run times; such as script based permission changes, or moving a folder, or changing fields in a content type.<\/p>\n
Incremental crawls don\u2019t remove \u201cdeletes\u201d, so ghost documents are still returned as hits, after deletion, until the next full crawl.<\/p>\n
SharePoint 2013 will introduce the concept of \u201cContinuous Crawl\u201d. It doesn\u2019t need scheduling. The underlying architecture is designed to ensure consistent freshness by running in parallel.<\/p>\n
Right now, if a Full or Incremental crawl is slow, everything else awaits its completion.<\/p>\n
It\u2019s a sequential crawl. Behind the scenes, continuous crawl selection results in the kick-off of a crawl every 15minutes (this wait can be configured) regardless of whether the prior session has completed or not.<\/p>\n
This means a change that is made immediately after a deep and wide-ranging change doesn\u2019t need to \u2018wait\u2019 behind it.<\/p>\n
New changes will continue to be processed in parallel as a deep policy change is being worked on by another continuous crawl session.<\/p>\n
Note that Continuous crawl will increase load incrementally on the SharePoint server since it inherently can run parallel multiple sessions simultaneously.<\/p>\n
If needed, we can tune this through \u2018Crawl Impact Rule\u2019 settings (which exist today in SP2010), which control the maximum number of simultaneous requests that can be made to a host (default is 12 threads, but it is configurable).<\/p>\n","protected":false},"excerpt":{"rendered":"
