1.给指定用户(tecamocmsuser)授权（ctxapp和execute on ctx_ddl）
grant ctxapp to tecamocmsuser;
grant execute on ctx_ddl to tecamocmsuser;
2创建分词
ctx_ddl.create_preference ('my_LEXER', 'chinese_vgram_lexer');
3创建索引
CREATE INDEX INX_Archive ON CMS_ODDITIONAL_ARTICLE (body) INDEXTYPE IS CTXSYS.CONTEXT PARAMETERS ('LEXER my_LEXER ');
4.数据同步
create or replace procedure PROC_SYNC_FULLTEXT
is
begin
ctx_ddl.sync_index('INX_Archive');
ctx_ddl.optimize_index('INX_Archive','FULL');
end;
5.定时同步
BEGIN
DBMS_JOB.ISUBMIT(job=>1010,what => 'begin PROC_SYNC_FULLTEXT ();end;',
next_date => SYSDATE, interval => 'SYSDATE + (1/24/12)');
commit;
END;
6.使用查询
select id from cms_odditional_article where contains (body, '广州')>1;
