Hello there,

I have a clutser with elasticsearch. I change the type of a field:  
`%{NUMBER:upload:int}`  
And now i get the error:  
`Mapping conflict! 3 fields are defined as several types (string, integer, etc)`  
As i understood reading on the discussions, i should reindex to get the type of the field.  
But i don't want to move the index, i jsut want to continuou with my system as it is.  
Just want to reindex, but i don't want to change the pattern logstash-\*

In fact, i don't understand clearly the process to reindex.

Any advice would be helpful.

Thanks
