> the field type solr.DenseVectorField introduced in solr 9.0 works well with 
> single core user managed and single shard collection in solr cloud way, but 
> in any multi shard collection it stores data as list of strings instead of 
> list of floats and running query on top of it also fails to provide correct 
> results.
>  
> attaching screenshot, the field name is vector, which is defined as 
> <fieldType name="knn_vector" class="solr.DenseVectorField" 
> vectorDimension="512" similarityFunction="cosine"/>
> {color:#000080}
> {color}
> <field name="vector" type="knn_vector" indexed="true" stored="true"/>
