Search and Classification (TREX) provides SAP applications with numerous services for searching, classifying, and text-mining in large collections of documents (unstructured data) as well as for searching in and aggregating business objects (structured data). TREX processes documents in a wide variety of formats and in more than 30 languages.
During installation of SAP NetWeaver, you can install TREX as a stand-alone engine, to make its functions available as part of an SAP NetWeaver IT scenario for the application in question.
