I have configured vector field in solr 9.8 version and have indexed documents having vector field. I am not able to figure out how many document indexed exactly have vector field. Other type of fields we can get doc count by "field_name:*" but vector field needs to have specific format. I am able to do vector query for specific queries but not for "*" query. Configuration for vector field in schema-

<fieldtype name="knn_vector" class="solr.DenseVectorField" vectorDimension="1024" />
<field name="doc_vector" type="knn_vector" indexed="true" stored="true"/>

Is there way to get format for all vector fields indexed doc count?
