hi guys,

i have similar string that i want to aggregate,  
but they seem to be different within few characters at the end.

for example:  
doc1: {"message":"hello world and good morning1 300"}  
doc2: {"message":"hello world and good morning1 200"}  
doc3: {"message":"hello world and good morning1 100"}

i would like to have this result in the aggregation:

"hello world and good morning1" - count: 3

the field currently defined with default analyzer

btw, is it possible to identify also more complected string such as:  
doc3: {"message":"500 hello world and good morning1 100"}

thanks a lot for advanced!

Lior
