SharePoint 2013 Administration : Enable & Modify Continuous Crawl

SharePoint 2013 includes a new type of crawl by the name Continuous Crawl that ensures the maximum possible refreshness of SharePoint Index.

1

The Continuous Crawl has got the ability to run in parallel and does not expect any previous crawl to get completed before the current one launched.

The Continuous crawl is available only for the SharePoint Index of type SharePoint Sites.

Once started a Continuous Crawl can be Paused or Stopped or Disabled

The default craw interval for Continuous Crawl is 15 minutes but this can be set to any appropriate value.

Since we don’t have any User Interface in SharePoint 2013 to set this value so we are left with only possibility i.e. by using PowerShell.

Enable Continuous Crawl : Central Administration

  • Go to Central Admin and Click on Manage Service Applications

2

  • Click on Search Service Application

3

  • On Search Administration Page click on the Content Sources link on the left navigation

  • On the SharePoint Index Settings Page, scroll down to Crawl Schedule section and select Enable Continuous Crawls radio button and save the settings.

6

Enable Continuous Crawl : PowerShell

$serviceApp = Get-SPEnterpriseSearchServiceApplication

$contentSource = Get-SPEnterpriseSearchCrawlContentSource -SearchApplication $serviceApp -Identity “Local SharePoint sites”

Set-SPEnterpriseSearchCrawlContentSource -Identity $contentSource -EnableContinuousCrawls $True

Modify Default Interval of Continuous Crawl : PowerShell

$serviceApp = Get-SPEnterpriseSearchServiceApplication

$serviceApp.SetProperty(“ContinuousCrawlInterval”, 5)

$serviceApp.Update()

Hope you find it helpful.
