Hi All,

I'm using Oracle 9i release 2.

Based on documentation, there are stoplists for different languages.
We already have english stoplist working and we want to include spanish stoplist also.

How can I do it?

Thanks in advance,
Ignacio.

I believe the default stoplist is only created for the primary language of your database. You can create an additional stoplist using ctx_ddl.create_stoplist. You can add stopwords to a stoplist using ctx_ddl.add_stopword. You can copy and paste the stopwords from the list in the documentation.

I'm reading at documentation:

"...Oracle Text provides default stoplists for most languages including English, French, German, Spanish, Dutch, and Danish. These default stoplists contain only stopwords..."

but, I don't find how to change default stoplist!

(visit http://download-east.oracle.com/docs/cd/B10501_01/text.920/a96518/cdatadic.htm#42833)

Thanks again,
Ignacio

Do you want to replace the default stoplist or add a spanish stoplist? What version of Oracle are you using? The default stoplist is created when the database is created, by running the appropriate sql scripts in the ctx/admin/default subdirectory of your Oracle home directory. If you want to add a stoplist, you can copy and paste the code from the appropriate sql file, modify it to change the name from default_stoplist to something else, like spanish_stoplist, so that it does not overwrite the existing stoplist, then run that file while logged in as ctxsys. In Oracle 10g, the file is <oracle_home>/ctx/admin/defaults/drdefe.sql for the spanish stoplist. In Oracle 9i, there is <oracle_home>/ctx/admin/defaults/drdefesa.sql for latin american spanish stoplist and <oracle_home>/ctx/admin/defaults/drdefe.sql for mexican spanish stoplist. Please let me know if you have any difficulties finding, modifying, or running the files.
