To fix this issue which is mainly for missing global lexer or due to missing of indexes

Step1:Running following queries for missing global lexer
Note: Prior to running check proper access to database user

Step2:For missing indexes
Run below query to get attributes  & object missing the indexes.

 select objectname,attributename from maxattribute where persistent=1 and searchtype='TEXT'
and objectname not in (select objectname from maxobject where isview=1)
and not exists (select 1 from user_indexes a,user_ind_columns b
where a.table_name=objectname and b.column_name=attributename
and a.index_name=b.index_name and a.index_type='DOMAIN');


For each object & attribute returned in above query create the indexes

CREATE INDEX indexname ON objectname (attributename)
INDEXTYPE IS CTXSYS.CONTEXT PARAMETERS
('lexer global_lexer language column LANGCODE');
