what is trex?

[Former Member · Accepted solution]

Its external search engine for SAP, we can buy this and install in the XI server.

ex : Suppose we have an order number, we don't no in which scenario it is used then we give this number to the TREX

then it searches and gives that scenarion name.

TREX is based on a client/server architecture. The client component is integrated into the

application that uses the TREX functions, and allows communication with the TREX servers.

The server component processes the requests; it indexes and classifies documents and answers

search queries.

HI

TREX is a product from SAP for searching and classifying large collections of documents. TREX stands for SAP NetWeaver Search and Classification (TREX) finds information in both structured and unstructured data.

TREX is a like a search engine which provides SAP applications to search structured and unstructured data.And it can read the images for the searching query.

How to find out which TREX patch/build level you on?

thanks

Hi,

TREX provides several client options:

Java client for communication via HTTP/XML in SAP EP

ABAP client for communication via RFC or ICM in SAP landscape

C++ and Python clients for internal calls and development

Inside TREX there are four main services:

Name server: manages TREX landscape, allocates TREX services

Index server: indexing and retrieval

Text-mining engine for classification and similarity search

Text search engine for search and indexing unstructured text Attribute/BIA engine for searching and indexing structured data

Queue server: manages asynchronous indexing

Preprocessor: document retrieval, filtering, linguistic processing

TREX Queue Server

􀂄 Collects indexing requests

u2013 Sends them to the index server

􀂄 Enables asynchronous indexing

u2013 Scheduled

u2013 Event triggered

􀂄 Includes scheduler for replication

u2013 Replication runs on index server

􀂄 Stores snapshots for replication

TREX Preprocessor

􀂄 Delivers documents that the engines can use directly

􀂄 Supports almost any data type

􀂄 Gets documents via HTTP from source

􀂄 Converts documents to HTML

􀂄 Keeps the document structure

􀂄 Extracts attributes

u2013 Metadata from DOC, PDF, ...

u2013 Names from a lexicon

u2013 Application-specific attributes

􀂄 Performs linguistic processing

u2013 Tokenization

u2013 Stemming

u2013 Tagging

(using third party products)

The TREX administration tool is the place to:

􀂄 Set up and configure a distributed landscape

􀂄 Monitor and administer services, indexes, queues, replication, ...

􀂄 Show trace files, configuration files, version info, ...

There are three flavors:

􀂄 Standalone

u2013 Richest feature set

u2013 Requires full access to TREX host

􀂄 ABAP

u2013 Restricted feature set

u2013 Easy access on customer systems

􀂄 Java

u2013 Highly restricted feature set

Thanks,

Hi,

Superordinate term for the TREX search engine, TREX text-mining engine, and TREX attribute engine.

For each component of an integration landscape that creates and persists messages (Integration Server, Adapter Engines and Integration Engines), a unique index can be created that contains all the messages of this component. The search and classification engine TREX is required for this purpose.

To configure a component for index-based message searching, you have to:

● ensure that the component is based on at least SAP NetWeaver u201804 Support Package Stack 15 (this is also valid for the J2EE Engine, on which your Runtime Workbench is running)

· establish a communication between the component and the TREX server

· set up and maintain the indexing of messages on this component

To enable an index-based message search in an integration landscape by using TREX, you require a TREX 6.1 or TREX 7.0 installation of the most current support package stack on a separate server.

○ For information about how to install TREX 6.1, see Installation Guide Search and Classification TREX 6.1 on SAP Service Marketplace at https://service.sap.com/instguidesNW04 ® Installation ® Cross-NW.

○ For information about how to install TREX 7.0, see Installation Guide u2013 TREX on SAP Service Marketplace at https://service.sap.com/instguidesNW04s ® Installation ® 3 u2013 Installation u2013 Standalone Engines.

TREX 7.0 support package stack 09 or above is required if you want to use the fast indexing mode for index-based messages searching. For more information, see Index Administration.
