| No need to implement the features completely, but we should at least experiment and check that we can add APIs easily. WARNING: We should at least try to implement a preliminary support for Elasticsearch aggregations, because there’s a high risk that our current APIs are not flexible enough to allow that without backward-incompatible changes. Examples:
Some of these features could be generalized and offered even with the Lucene backend, while some may be better implemented as backend-specific features |
