Hi Guys........

Apologies........

Please Correct me If I am wrong,

with refrenc to
http://issues.apache.org/eyebrowse/ReadMsg?listId=30&msgNo=7103

I will have to Re - Index all my 1 Million subindexes with the 'Price
FieldType'  padded of to  standard no of '0' s.

So can use the code modified   while Searching to find the range of Query...


[   Is there any other way to  handle this Only during SearchProcesss... ]


 Please some more Advise....                :(
