Advanced Configuration

The advanced configuration comprises the following areas:

• Language Recognition and Processing with TREX

  TREX supports the indexing of documents that exist in different languages. When TREX is installed, you select the languages to be identified by language recognition. You can retrospectively configure TREX to recognize additional languages.

• File Formats Supported by TREX

  Documents whose content and attributes can be indexed and searched by TREX can exist in numerous different file formats. You can configure which file formats you want to exclude from processing and which parts of XML and HTML files you want to exclude from indexing.

• Changing Proxy Server Settings

  The TREX preprocessor can access documents on Web pages using a proxy server. You can configure the settings for the proxy server.

• Configuring the Python Extensions

  Some TREX functions are implemented as Python extensions. If the application from which TREX is used uses these functions, you have to activate the Python extensions.

• Configuration of the TREX Services in the SAP J2EE Engine

  The TREX Java client is implemented as a TREX service in the J2EE engine. You can use the SAP NetWeaver Administrator to configure TREX caches and the TREX Java client.

• Configuration of the Delta Index

  TREX provides the option of activating delta indexes. This allows you to update indexes faster and improve the performance of TREX.

• Changing the TREX Host Name (Single and Multiple Hosts Installation)

  You can change the name of the host on which you installed TREX later on, or you can install TREX with a virtual host name right from the start. You can do this for both single-host and multiple host installations.

• Configuration of the TREX Security Settings

  You can configure secure communication between TREX and the application using it (for example, SAP Enterprise Portal or SAP Customer Relationship Management).
