==== Deprecation of sparse vector fields
|
|
The `sparse_vector` field type has been deprecated and will be removed in 8.0.
|
|
We have not seen much interest in this experimental field type, and don't see
|
|
a clear use case as it's currently designed. If you have feedback or
|
|
suggestions around sparse vector functionality, please let us know through
|
|
GitHub or the 'discuss' forums.
|
|

|
|
==== Update to vector function signatures
|
|
The vector functions of the form `function(query, doc['field'])` are
|
|
deprecated, and the form `function(query, 'field')` should be used instead.
|
|
For example, `cosineSimilarity(query, doc['field'])` is replaced by
|
|
`cosineSimilarity(query, 'field')`.
|

|
==== Disallow use of the `nGram` and `edgeNGram` tokenizer names
|
|
|
|
The `nGram` and `edgeNGram` tokenizer names haven been deprecated with 7.6.
|
|
Mappings for indices created after 7.6 will continue to work but emit a
|
|
deprecation warning. The tokenizer name should be changed to the fully
|
|
equivalent `ngram` or `edge_ngram` names for new indices and in index
|
|
templates.
