MarkLogic 9 Product Documentationclang 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.
