Trex Indices Test
The index server indexes and classifies documents and answers search queries. The processing takes place in the engines that belong to the index server. There are the following engines:
- Search engine: This engine is responsible for standard search functions such as the exact, error-tolerant, linguistic, Boolean, and phrase searches.
- Text-mining engine: This engine is responsible for classification, searching for similar documents (‘See Also’ search), the extraction of key words, and so on.
- Attribute engine: This engine is responsible for searching for document attributes such as author, creation date, and change date.
This test auto-discovers the indices available in the SAP TREX server and reports the current status of each index. In addition, this test helps administrators figure out the effectiveness of each index.
Target of the test : A SAP TREX
Agent deploying the test : An internal agent
Outputs of the test : One set of results for each Index type:Index of the target SAP TREX server that is to be monitored

The values reported by this measure and its numeric equivalents are mentioned in the table below:
Note: By default, this measure reports the Measure Values listed in the table above to indicate the current status of this index. The graph of this measure however, represents the status of a server using the numeric equivalents only - 0 to 7. |

Optimized documents: |
Indicates the number of documents that were optimized for this index. |

A low value is desired for this measure. If too many documents are optimized i.e., if the index server performs frequent optimization, then the index server also rewrites the index frequently affecting the performance of the index. |
