Hi,

I'm upgrading from 1.X to 5.X (finally ...phew...)  
I'm facing an issue with FilterBuilder. At present (1.3.2) my code is  
**FilterBuilders.notFilter(FilterBuilders.termFilter(key,value);**  
How do i convert the above code to work in 5.5.1?

try a `bool` query with a `must_not` clause in the `filter` part of another boolean query (on top of my head, not tested).
