Crawler Definition

iKnowBase provides an integration adapter to Oracle Secure Enterprise Search. To use this, you need to create a Crawler definition which specifies which data to be indexed.

The related concepts are as follows:

An iKnowBase Search source specifies what data is available to the external search engine, across two axis. In many ways, the Search source defines the document corpus available to the search engine.
It specifies the set of documents / information object, as a "where condition on the document table.
It specifies the set of attributes / columns to be included.
A Crawler definition adds state to a Search source. Where as a Search source only specifies a point-in-time snapshot of documents and attributes, the crawler definition makes it possible to see the difference between various points in time.
The iKnowBase SES Connector is set up as a SES Crawler to crawl a document corpus, based on the ID of the Crawler definition.

See Development Guide for further information.

Properties

This section describes the properties of a crawler definition, as shown on the corresponding Edit pane tabs.

Edit Tab

The edit tab contains all the properties of a crawler definition, together with statistics of the latest crawl.

Property	Description
Subsystem	Select the appropriate subsystem.
Title	Type a name for the crawler.
Description	Type a description for this crawler.
External key	Type an external key to be used in SES as crawler identification (instead of the ID).
Search source	Select the appropriate search source, where the document selection is defined.
Domain	Specifies the domain the SES-installation should be executed in. This is used to control the target selector (homeplace) used when the document is finally opened. If you are running a public SES instance, it also defines the Public iKnowBase user to be used.
URL to open the document	The crawler needs to know how to open the document. This URL points to the iKnowBase redirect engine. This should point to the “/go/crawler” URL under the ikbViewer. Normally, use http://www.example.com/go/crawler, replacing the host and port number as required.
Show top node for dimensions	Select this check box to specify if a dimensional value should show the top node of the dimension.
Status	It displays the crawler status. READY: Indicates that the crawler can be executed. PROGRESS: Indicates that the indexing process is currently being executed.
Last runned	Displays the last indexing date.
#Documents	Displays the total number of documents indexed during the latest run.
#New	Displays the number of new documents since the last run.
#Changed	Displays the number of changed documents since the last run.
#Deleted	Displays the number of deleted documents since the last run.
Guid	Displays a globally unique identifier number for this component. This property appears after you save a component. You cannot update the information of this property.
Id	Displays a unique identifier number for this component. This property appears after you save a component. You cannot update the information of this property.
Created	Displays when the component was created and by whom it was created.
