Hi,
we have some other minor information that might help in debugging this error:
We index the embeddings as nested fields and can reproduce the error with the
following code:
String q = "{!knn f=vector topK=20}[0.031046804...";
SolrQuery sq = new SolrQuery("{!cache=false}" + q);
sq.addField("score"); // no error without the score field
sq.setRows(14); // Defect document must be included in result
sq.setSort("ID", ORDER.asc); // Order is not important, but ID is. No error
e.g. with score
final QueryRequest r = new QueryRequest(sq, METHOD.POST);
SolrClient solrClient = SolRConnector.createServer(server);
QueryResponse response = r.process(solrClient);
We checked that the child document with the document id is present in the index.
