Describe the problem
I’m using MilvusClientV2.listIndexes(ListIndexesReq) to check and auto-create indexes on specific vector fields before loading a collection into memory. According to the official documentation, listIndexes accepts both collectionName and fieldName, so I expected it to return only the indexes defined on that field. In practice, however, it ignores fieldName and returns all index names in the collection.
What I found in the code
listIndexes builds a DescribeIndexRequest with the provided fieldName, calls the gRPC stub’s describeIndex(...), but then simply maps every returned IndexDescription to its indexName without any client-side filtering.- The SDK’s separate
describeIndex wrapper does filter by fieldName (or indexName) after the RPC, but listIndexes does not.
Expected behavior
- If
fieldName is supplied, listIndexes should return only the index names that correspond to that field.
- If the intention is to always return all indexes, then the
fieldName parameter should be removed from ListIndexesReq to avoid confusion.
Suggested fix
In GrpcMilvusClient.listIndexes, after receiving the DescribeIndexResponse, add a filter step such as:
response.getIndexDescriptionsList().stream()
.filter(desc -> request.getFieldName() == null
|| desc.getFieldName().equals(request.getFieldName()))
.map(IndexDescription::getIndexName)
.collect(Collectors.toList());
