Breaking Changes in Nested Filter

[klappvisor]

According to documentation of elasticsearch v0.90.9 nested filter has been changed and looks slightly different now. Also scope support has been removed (elastic/elasticsearch#2606) from queries and filters. I'd like to contribute but this is important breaking changes and I think it would be better to ask you first about your plans to introduce breaking changes in NEST?

Any way it seems to be necessary to introduce these breaking changes because elasticsearch server throws an exception about _scope...

This is a difficult one,

I'm working hard one the https://github.com/Mpdreamz/NEST/tree/api-changes branch to stabilise my own IElasticClient api which will make the typed calls itself really easy to implement (see https://github.com/Mpdreamz/NEST/blob/api-changes/src/Nest/ElasticClient-Validate.cs)

I was going to release this as NEST 0.90.0 and use the 0.90.0 range as the last batch of versions to support the 0.90.* versions of elasticsearch

Elasticsearch 1.0 introduces several breaking changes (aliases, percolator have substantially changed amongst others).

NEST 1.0 will be compatible with elasticsearch 1.0 and integration tests will run only on elasticsearch 1.0.
NEST 0.90 will be compatible with elasticsearch 0.90.*

I'll support the 0.90 branch of NEST for atleast a year

This breaking change complicates my plans to accomodate the jump to 1.0 though. Will have to think about this! Suggestions welcome!

@klappvisor it took a while but this has now been added (removing scope and adding join property to nested filter).

Thanks for opening the issue !
