Problem With Match Transformation

Question

Hi ,
I am using Match transformation to find the duplicates .
My input data like this
EMP NO     ENAME         SAL     DEPTNO
10     SRIRAM MV  10000     100
11     MV SRIRAM  11000     100
12     SRIRAM PV  11000     100
13     SRIHARI       11000     100
14     SUBBIAH       11000     100
15     RAMANA       11000     100
Iam finding the duplicates on Ename .
My ename data like SRIRAM MV, MV SRIRAM  like that data . both are duplicate records . for that iam using WORD SIMILARITY  option instead of field similarity with match score is 100 and no match score is 99.
But i am getting all are unique records .
If i am using match score is 85 and no match  score is 84 then iam getting the result like this .
EMP NO     ENAME     SAL     DEPTNO     GROUP_NUMBER     MATCH_STATUS     MATCH_SCORE
11     MV SRIRAM     11000     100     1     P     94
15     RAMANA     11000     100          U     
13     SRIHARI     11000     100          U     
10     SRIRAM MV     10000     100     1     D     
12     SRIRAM PV     11000     100     1     P     88
14     SUBBIAH     11000     100          U     
means MV SRIRAM,SRIRAM MV ,SRIRAM PV  comes under one group number with SRIRAM MV  as driver and MV SRIRAM as passenger with 94 similarity score and  SRIRAM PV as passenger with 88 score.
While i am using the match score i need to get 100% per SRIRAM MV and MV SRIRAM . then whats the settings needed to get correct result. whats the problem with my settings.
Please help me out to solve the problem
Thanks&Regards,
Ramana.

Ramana,
<<< My ename data like SRIRAM MV, MV SRIRAM like that data . both are duplicate records . for that iam using WORD SIMILARITY option instead of field similarity with match score is 100 and no match score is 99. >>>
You are looking for an exact match here, but MV SRIRAM and SRIRAM MV are not exactly the same.  The characters MV are in different positions.  The Word Similarity option compares words instead of the entire field, but the character position also affects the match score.
<<< While i am using the match score i need to get 100% per SRIRAM MV and MV SRIRAM . >>>
You cannot force the the match score to be a specific value.  SRIRAM MV and MV SRIRAM are not a 100% match and never will be.  What you need to do is adjust the match settings so that the dupe group includes SRIRAM MV and MV SRIRAM but excludes SRIRAM PV.  Try Match Score = 90 and No Match Score = 89.
