Tab Page: Metadata Indexing
Definition
Under Administration in the Data Warehousing Workbench, you can use 
on the Metadata Indexing tab to check the required settings for the metadata search, and to index the metadata.
Structure
The Metadata Indexing tab has the following fields and functions:
Status Display
|
Field |
Description |
|
Status of Search Engine |
The system indicates whether the TREX server is configured correctly. Display options: OK/Not Fully Installed |
|
Status Search/Indexing |
The system displays the indexing and search status.
|
|
RFC Connection |
The system displays the current RFC connection to the TREX search engine. If you want to use a different RFC connection, use input help in the BW system to select one. |
Indexing
In general, an indexing with default settings is sufficient.
By choosing Schedule Initial and Delta Indexing, you start indexing with the default settings: The system performs an initial indexing run, followed by delta indexing every five minutes.
Delta Indexing with Default Settings
|
Field |
Description |
|---|---|
|
Status of Indexing Job |
The system indicates whether the indexing job has been 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 frequency of 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:
The Start Time dialog box appears. Confirm that the indexing program should run as a regular job. This ensures that the index queue is processed regularly.
The Initial Index for TLOGO Objects in TREX Server screen appears.
You can specify whether 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. In the default setting, the logon language is predefined.
A screen with a list of all the object types relevant to the BW 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 flag. The system can then only search for the object type in a database search. This is a slower, case-sensitive search option that does not support searching for attributes.
If you reselect active objects for the search or indexing, you should perform an initial indexing.
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 considerably more time.
To reactivate the TREX search, you need to perform initial indexing again.
