Where is boolFilter().cache and hasParentFilter in ES 2.x?

[apanimesh061]

Following is a snippet that is compatible with ES 1.x:
BoolFilterBuilder boolFilterBuilder = boolFilter().cache(true);

This is a function present in FilterBuilders.java:
hasParentFilter(String parentType, QueryBuilder query)

How do I change the syntax to make it compatible with ES 2.x?
I could not find any examples?

Hi apanimesh061,

the main reason is that queries and filters have been merged in 2.0.

To your specific issues:

• bool filter has been replaced by bool query in 2.x, so you basically have to use QueryBuilder now.
• Also note that Elasticsearch decides internally whether to cache a filter, so there is no need for a cache(boolean) method anymore.
• The has_parent filter is now has_parent query. You can use the HasParentQueryBuilder for that.
