clang functions

The table below lists all the clang built-in functions (in this namespace: http://marklogic.com/xdmp/custom-language).

Use the custom language management functions to configure plugin stemmers and tokenizers for specific languages in MarkLogic Server. The custom language module is installed as the following file:

  • install_dir/Modules/MarkLogic/custom-language.xqy

where install_dir is the directory in which MarkLogic Server is installed.

Many of these functions provide new configuration information. You must explictly update the configuration by calling clang:language-config-write in the same statement that you use the functions in order for them to take effect.

To use the this module in your own code, include the following line in your XQuery prolog:

import module namespace clang = "http://marklogic.com/xdmp/custom-language" at "/MarkLogic/custom-language.xqy";

The library namespace prefix clang is not predefined in the server.

Calling clang:language-config-write restarts the server so that your changes can take effect.

For more details, see Configuring Tokenization and Stemming Plugins in the Search Developer's Guide.
