Oracle 12.1c Enterprise. Context index
Using Multi_lexer, with Multi_stoplist
exec ctx_ddl.create_stoplist('MultiStop','MULTI_STOPLIST');
exec ctx_ddl.add_stopclass ('MultiStop', 'longwords', '[[:alnum:]]{20,}')
Index a document with base64 encoded text attachments,
select length(token_text) len, i.* from table$I i
order by 1 desc
I get records with length 64 which apparently is the default max. Should be 20 if it worked.
Question: Does stopclasses using regex even work with multi_lexer/multi_stoplist?
