==== TokenizerFactory changes
|
|
|
|
|
|
|
|
|
|
TokenizerFactory now has a `name()` method that must be implemented. Most
|
|
|
|
|
plugin-provided TokenizerFactory implementations will extend `AbstractTokenizerFactory`,
|
|
|
|
|
which now takes a `name` parameter in its constructor.

==== Forbid empty doc values in vector functions
|
|
|
|
|
If a document doesn't have a value for a vector field (dense_vector
|
|
|
|
|
or sparse_vector) on which a vector function is executed, an error will
|
|
|
|
|
be thrown.
