Lower/UpperCase Issue

[EXTERNAL Taminidi Ravi (ETI, Automotive-Service-Solutions)]

I have a situation here, when I search with "BALANCER" the results are 
different Compare to "Balancer" and the order is different  When I search 
"BALANCER" then, the documents with Upper Case are first in the List and for 
"Balancer" it is in different order.

I am confused why this behavior, Can some one has same issue or I am missing 
something.
