About Content Service Development
Content services allow you to search external repositories
through the portal and index external content in the portal Directory.
These services allow users to access documents and other resources
from multiple repositories without leaving the portal workspace.
- Content crawlers access content from an external repository
and index it in the portal. Portal users can search for and open crawled
files through the portal Directory. Content Crawlers can be used to
provide access to files on protected back-end systems without violating
access restrictions. Content Crawlers are implemented as remote web
services. For details, see About Content Crawlers.
- Federated search services are remote web services that
search external repositories, including the web, internal company
databases and document repositories. For details, see About Oracle WebCenter Interaction Federated Search Services. For additional search customization options, see the Oracle WebCenter Interaction UI Customization Guide.
