Symptoms

-- Problem Statement:
Slow indexing performance while trying to index a table with around 1000 records when Arabic index_stems is enabled.

begin                                                          

 ctx_ddl.drop_preference('ABC_LEXER');

 ctx_ddl.create_preference('ABC_LEXER', 'BASIC_LEXER');

  ctx_ddl.set_attribute ( 'ABC_LEXER', 'index_stems', 'ARABIC');

end;

/

Disabling 'index_stems' tends to result in good and fast indexing.
