What Is An Oracle Ultra Search Apis?

Answer»

Oracle Ultra Search provides the following APIs:
1) The query API works with indexed data. The Java API does not impose any HTML rendering elements. The application can completely customize the HTML interface.
2) The crawler agent API crawls and indexes proprietary document repositories. The e-mail Java API accesses archived e-mails and is used by the query application to display e-mails. It can also be used to BUILD our own custom query application.
3) The URL rewriter API is used by the crawler to filter and rewrite extracted URL links before they are inserted into the URL QUEUE.
4) The Document Service crawler agent API enables GENERATION of attribute data based on the document contents. It accepts robot metatag instructions from the agent for the target document, and it TRANSFORMS the original document contents for indexing control.
