How to configure SQL Anywhere to use an external term breaker

By default, when you create a text configuration object, a built-in term breaker is used for data associated with that text configuration object. To have data instead pass through an external term breaker library, you specify the library and its entry point function using the ALTER TEXT CONFIGURATION statement, similar to the following:

ALTER TEXT CONFIGURATION my_text_config 
   TERM BREAKER GENERIC EXTERNAL NAME 'my_termbreaker@termbreaker'

This example tells the database server to use the my_termbreaker entry point function in the termbreaker library to obtain a term breaker instance to use when building, updating, or querying a text index associated with the my_text_config text configuration object, when parsing the text configuration object's stoplist, and when processing input to the sa_char_terms system procedure.
