java filtered query requires query

[brackxm]

queryBuilder is not Nullable in FilteredQueryBuilder.
Using json/http it is optional.
Example in the documentation:
http://www.elasticsearch.org/guide/en/elasticsearch/guide/current/_filtering_queries_and_aggregations.html

The workaround is to use a matchAllQuery.

Thanks for the report, this looks wrong indeed.

[brackxm]

Is there a performance difference between a matchAllQuery and no query?

[jpountz]

No. Actually the parser uses a match_all query when no query is specified, so this is mostly equivalent, the only thing that you pay for is the serialization of the match_all query, but that should be nothing.

not sure how adoptme is supposed to work, but i'll have a go
