MULTI_LEXER Restriction

MULTI_LEXER must have a sublexer specified for different languages. If you already know the language, you can use BASIC_LEXER as the sublexer. If the language is not known, then you use AUTO_LEXER instead of MULTI_LEXER. Hence, using AUTO_LEXER as a sublexer of MULTI_LEXER is not useful and it is disabled.

Thus, the following statements will not work and throw error DRG-13003.

exec ctx_ddl.create_preference ('multilexer', 'MULTI_LEXER');
exec ctx_ddl..create_preference('autolexer', AUTO_LEXER);
exec ctx_ddl.add_sub_lexer('multilexer', 'GERMAN', 'autolexer');
