No record return

Question

Hi all,
I am using the below query to run it against oracle database to do searching. when i run this query to return all the records with something like 'Du.................'
It just give me a blank page and when I run the database without using this part AND (V.VNAMEL like '%'||upper('&NAMEL ')
OR V.VNAMEL like upper('&NAMEL ') ||'%'
OR V.VNAMEL like '%'||Upper('&NAMEL ')||'%')
I am getting what i wanted. It is just a puzzle to me why this is not working.It works for anything except when i use something that start with 'DU..'
can someone take a look at and let me know what is going on.
I really appreciate your time and help

try this
AND  V.VNAMEL like '%'||upper('&NAMEL')||'%'
or this
AND  instr(upper(V.VNAMEL),upper('&NAMEL')) > 0
SELECT DISTINCT V.VENDOR , R.ADDRNUM , V.VNAMEL , R.AADDR1 , R.ACITY,
                R.ASTATE ,R.AZIPCODE , R.APHONE , MAX(P.DATEPUR)
  FROM VENDOR V,VENDADDR R,PLANHOLD P
WHERE V.VENDOR = R.VENDOR
   AND V.VNAMEL like '%'||upper('&NAMEL')||'%'
  AND P.VENDOR   = R.VENDOR
  AND P.DATEPUR >= TO_DATE('2002-01-01','YYYY-MM-DD')
  AND V.VOBSOLET = 'N'
GROUP BY V.VENDOR, R.ADDRNUM, V.VNAMEL, R.AADDR1, R.ACITY, R.ASTATE,R.AZIPCODE, R.APHONE
or
SELECT DISTINCT V.VENDOR , R.ADDRNUM , V.VNAMEL , R.AADDR1 , R.ACITY,
                R.ASTATE ,R.AZIPCODE , R.APHONE , MAX(P.DATEPUR)
  FROM VENDOR V,VENDADDR R,PLANHOLD P
