Does the knn field support array values?

eg. { "my_vector1" : [[1.5, 2.5], [2, 3], [3.5, 5]], "price":10 }

Hi @wrkaiser, at this point we do not support array values. You could add multiple fields in the index and add vectors in a single document. If you are looking into index into a single field, then every document should have one vector

Thx~~ I considered that you said, but the number of value is not fixed.

[vamshin]

Sorry what do you mean by number of value is not fixed?

[wrkaiser]

The length of array no fixed.

example,~ doc1: {"my_vector1" : [[1.5, 2.5], [2, 3], [3.5, 5]]} doc2: {"my_vector1" : [ [2, 7], [3, 3]]}

You will add one vector per document i.e each element of array which is a vector will be indexed in one document of Elasticsearch. As the number of vectors increase documents would increase.
