operators to accept a missing or null value in a field used in the join.
Improvements
- Upgraded to Elasticsearch 7.17.18
- Added the truncation trace in search requests executed with the adaptive query planner.

within
operator by doing a merge overlap optimization. - Implemented a pre-filtering technique in spatial joins to reduce unnecessary index lookup operations.
- Enhanced the data type compatibility check for fields used in a join.
- Introduced a new resource management layer in the adaptive query planner.

Bug fixes

class cast exception
from occurring when projecting fields in a multi-conditional index join. - Fixed an issue that created a stage node for a cached join in the adaptive query planner.

indices
join query clause. - Fixed an issue with the creation of
function_score
queries when theboost_mode
parameter isn’t passed explicitly. - Fixed an incomplete response when doing an aggregation and no index could match the request due to a date range filter.
