I execute below query on sql prompt. But this is not giving any result although it have rows corresponding to 'with' in table.

It is working fine with any other string except string 'with' and 'inc'.

select rownum rn, text from accumtbl
where contains(text,'with')>0
no result found

pls help to sort out problem. Why it is not working with only 'with' and 'inc'.
