Tab Page: Metadata Indexing 

Definition

In the Administration functional area of the Data Warehousing Workbench, you can use  Metadata Search/Documents and then the Metadata Indexing tab page to check the required settings for the metadata search, and to index the metadata.

Structure

The Metadata Indexing tab page has the following fields and functions:

Status Display

Field	Description
Status of Search Engine	The system displays whether the TREX server is configured correctly. Display options: OK/Not Fully Installed
Status Search/Indexing	The system displays the indexing and search status. ●     Not Indexed ●     Indexing in Progress ●     Indexing Complete
RFC Connection	The system displays the current RFC connection to the TREX search engine. If you want to use a different RFC connection, select another RFC connection in the BI system using input help.

For more information about installing the search engine and creating and entering an RFC connection, see SAP Reference IMG → SAP Customizing Implementation Guide → SAP NetWeaver → Business Intelligence → Connectivity of TREX.

Indexing

In general, an indexing with default settings is sufficient.

By choosing Schedule Initial and Delta Indexing, you start the indexing with the default settings: the system performs an initial indexing; this is followed by the delta indexing every five minutes.

Delta Indexing with Default Settings

Field	Description
Status of Indexing Job	The system displays whether the indexing job was scheduled. Display options: Scheduled/Not Scheduled
Start Date	The system displays the date and time of the scheduled execution of the indexing job.
Frequency	The default value for the execution of the delta indexing is every five minutes.

If you want to make additional settings, use Special Functions to choose expert mode.

The following functions are available in expert mode:

 Schedule Delta Indexing

The Start Time dialog box appears. Specify that you want the indexing program to run as a regular job. This ensures that the index queue is processed regularly.

 Initial Indexing

The Initial Index Built for TLOGO Objects in TREX Serverscreen appears.

You can choose whether you want to index one or all object types, active or content objects.

You can trigger a new index by choosing Delete Data Indexed Before.

In expert mode, you can enter one or more object names and languages and start indexing again with restricted criteria. By default, the logon language is predefined.

 Configure Object Types for Search

A screen with a list of all the object types relevant to the BI metadata search and the related search/index status appears. The selected object types are available for indexing and search.

You can exclude individual object types from the search or indexing by deselecting the indicator. The system can then only search for the object type in a database search. This is slower, the system distinguishes between upper and lower case letters, and searches for attributes are not supported.

If you reselect active objects for the search or indexing, you should perform an initial indexing.

Note that an object type is available for indexing and search after it has been selected. However, the last change made to the object type is only implemented in the index when you perform initial indexing again.

 Delete Index

If you delete the index, the TREX search is deactivated. (The indexing status changes to Not Indexed.) When a search request is made, the system reads from the database; this requires significantly more time.

To reactivate the TREX search, you need to perform initial indexing again.

Monitor

Field	What You Need to Know
Job Overview	The Simple Job Selection screen appears. The Job Name field contains the name of the indexing job. You can also restrict the jobs to be displayed in the overview with respect to Job Status, Job Start Condition, and Job Step. To display a scheduled job, you must select the Planned option under Job Status. For more information, choose  Information. Choose  Execute. The Job Overview screen appears. For more information, see Managing Jobs with the Job Overview.
Indexing Logs	The Analyze Application Log screen appears. To display the initial and delta indexing logs, enter the following external identifiers: * : Logs for initial and delta indexing  INITIAL_INDEX: Logs for initial indexing ID DELTA_INDEX: Logs for delta indexing Choose  Execute.

Metadata Search

Field	What You Need to Know
Search	You start the BI metadata search on the Simple Search screen.
