Configure crawl settings for a ServiceNow instance external content connector

Specify the content types that you want your ServiceNow instance external content connector to retrieve when running content crawls.

시작하기 전에

A connector admin must have already created the ServiceNow® instance external content connector that you want to configure crawl settings for. To learn about this procedure, see Create a ServiceNow instance external content connector.

This task is optional. By default, the ServiceNow instance external content connector retrieves all KB articles from your ServiceNow AI Platform instance. You only need to perform this task if you want the connector to use inclusion or exclusion filters for the KB articles to retrieve when running content crawls.

Content is only retrieved from the source system if it passes all of your configured crawl setting filters. If any crawl setting filter excludes a content item, the external content connector doesn't retrieve it.

중요사항:

By default, each external content connector can index up to ten million (10,000,000) content items from its source system. When a connector exceeds this limit, it continues to crawl the source system, but only sends content item deletions and updates to AI Search for indexing, ignoring new content items. The connector logs an error message for every 10,000 content items it crawls beyond the indexing limit.

When a connector's indexed content item count exceeds 800,000, a warning message appears in the connector's UI to indicate that it's approaching the indexing limit. If the connector reaches the indexing limit, an error message appears in its UI.

External content connectors that support user permissions crawls can retrieve up to five hundred thousand (500,000) users.

If one of your connectors reaches the content indexing limit, you can update its crawl settings and file inclusion/exclusion filters to reduce the number of content items it retrieves. Alternately, if you need a connector to index more than 10,000,000 content items or to retrieve more than 500,000 users, you can create a Customer Service and Support case at https://support.servicenow.com/now to request a limit increase for the connector.
