Features

Some of the features of the SharePoint 2016 connector include:

  • Performs incremental crawling (so that only new/updated documents are indexed) using Aspire Snapshots.*
  • Fetches access control lists (ACLs) for document level security.
  • Is search engine independent.
  • Runs from any machine with access to the given SharePoint URLs.
  • Supports NTLM and HTTPs.
  • Support for BCS external lists.
  • Designed for supporting early binding mechanisms.
  • Runs without installing anything on SharePoint.
  • Regular expression patterns for files to include / exclude.


Change Log Incremental

From version 3.3.0.1 incremental crawls using SharePoint's Change Log is available as an option in the connector's configuration.


Content Retrieved

The SharePoint 2016 connector retrieves several types of documents. Listed below are the inclusions and exclusions of these documents.

Include

  • Sites
  • Lists
  • External Lists (BCS)
  • Folders
  • Documents or List Items
  • Attachments

ListItems can take a number of different formats. For example, documents (pdf, doc, ppt, etc), calendar events or announcements. For more info on how ListItems content types work go to the MSDN article.


Limitations 

Due to API limitations, SharePoint 2016 connector has the following limitations:

  • The connector uses the REST API to access SharePoint database(s) directly; it doesn't do web crawling.
  • Crawling is only supported using a Site or a List as a root url.
  • SharePoint Change Logs for incremental crawling is not supported.*


To use SharePoint 2016 Connector version 3.3, version 3.3.0.1 of the Aspire Connector Framework is required.


Change Log Incremental

From version 3.3.0.1 incremental crawls using SharePoint's Change Log is available as an option in the connector's configuration.



Future Development Plan 

The following features are not currently implemented, but are on the development plan:

  • Support SharePoint Change Logs for faster incremental crawling
