Upgrading from 5.2.x to 5.3.x
This section describes breaking changes from version 5.2.x to 5.3.x and how removed features can be replaced by new introduced features.
Breaking Changes
During the parameter replacement in @Query annotated repository methods previous versions wrote the String "null" into the query that was sent to Elasticsearch
when the actual parameter value was null. As Elasticsearch does not store null values, this behaviour could lead to problems, for example whent the fields to be
searched contains the string "null". In Version 5.3 a null value in a parameter will cause a ConversionException to be thrown. If you are using "null" as the
null_value defined in a field mapping, then pass that string into the query instead of a Java null.
