How to use LIKE Operator with my query requriment

Question

HI all,
I have a requirement as follows
EMPID ENAME JOB SAL
10 RAJ KAMAL MANAGER 25000
20 KAMAL RAJ NAYAK CLERK 4000
30 NARENDAR GUPTA ANALYST 20000
40 ASHUTOSH GUPTA DEVELOPER 10000
50 ASHUTOSH NAYAR PROGRAMMER 15000
i am searching enames such that i need to get the whole name even if i search with just a single LETTER/WORD immaterial of the order they exist in the name for which i need to get the whole name.(INFACT WORD comparision)
ex:
1) select * from emp where ename like '%ka%'
i am getting:
10 RAJ KAMAL MANAGER 25000
20 KAMAL RAJ NAYAK CLERK 4000
This is not what i need i need just word camparision not letters comparision let me tell you...
select * from emp where ename like '%amal%'
Even for this query ill get the same output.. this is not my option to go..
I need just word comparision with starting letter and immaterial of the word position in the name
If it is possible to do with query please let me know..
Thanking you
