Is there an existing issue for this?

Current Behavior

• image: master-20240402-bd853be8c-amd64

case:

	mc := createMilvusClient(ctx, t)

	// create -> insert [0, 3000) -> flush -> index -> load

The same as SORT index: "STL_SORT are only supported on numeric field"

// Sort scalar index only supported on numeric field
func TestCreateSortScalarIndexUnsupportedDataType(t *testing.T) {
	ctx := createContext(t, time.Second*common.DefaultTimeout*2)
	// connect
	mc := createMilvusClient(ctx, t)

	// create -> insert [0, 3000) -> flush -> index -> load
	cp := CollectionParams{CollectionFieldsType: AllFields, AutoID: false, EnableDynamicField: false,
		ShardsNum: common.DefaultShards, Dim: common.DefaultDim}

	dp := DataParams{DoInsert: true, CollectionFieldsType: AllFields, start: 0, nb: common.DefaultNb,
		dim: common.DefaultDim, EnableDynamicField: false}

	// index params
	ips := []IndexParams{{BuildIndex: false}}
	lp := LoadParams{DoLoad: false}
	collName := prepareCollection(ctx, t, mc, cp, WithDataParams(dp), WithIndexParams(ips), WithLoadParams(lp),
		WithCreateOption(client.WithConsistencyLevel(entity.ClStrong)))

	// create Trie scalar index on varchar field
	coll, _ := mc.DescribeCollection(ctx, collName)
	idx := entity.NewScalarIndexWithType(entity.Sorted)
	for _, field := range coll.Schema.Fields {
		if supportScalarIndexFieldType(field.DataType) {
			if field.DataType == entity.FieldTypeVarChar {
				err := mc.CreateIndex(ctx, collName, field.Name, idx, false, client.WithIndexName(field.Name))
				common.CheckErr(t, err, false, "STL_SORT are only supported on numeric field")
			} else {
				err := mc.CreateIndex(ctx, collName, field.Name, idx, false, client.WithIndexName(field.Name))
				common.CheckErr(t, err, true)
				// describe index
				indexes, _ := mc.DescribeIndex(ctx, collName, field.Name)
				expIndex := entity.NewGenericIndex(field.Name, "", idx.Params())
				common.CheckIndexResult(t, indexes, expIndex)
			}
		}
	}
