Oracle Secure Enterprise Search provides the following APIs:
The Web Services APIs are used to integrate Oracle SES search capabilities into your search application. Oracle SES provides Java proxy libraries. You either can use the Java libraries or create proxies, based on the published Web Services Description Language (WSDL) files, to access Oracle SES Web Services. Oracle SES provides two Web Services APIs:
Query Web Services API
Administration Web Services API
Oracle SES includes an extensible crawler plug-in framework that lets you crawl and index proprietary document repositories with the Crawler Plug-in API.
Oracle SES also includes an extensible authentication and authorization framework. You use any identity management system to authorize users with the Identity Plug-in API, and you can define your own security model for each source with the Authorization Plug-in API.
The URL Rewriter API is used by the crawler to filter and rewrite extracted URL links before they are inserted into the URL queue.
The Query-time Authorization API filters search results and access to document information at search time. Query-time filtering can be used in addition to, or instead of, ACLs.
