А полный пример можешь скинуть?
t = box.schema.create_space("test")
t:format({{name = "id", type = "number"}, {name = "col1", type = "string"}})
t:create_index('primary')
t:create_index("col1_idx", {parts = {{field = "col1", type = "string", collation = "unicode_ci"}}})
t:insert{1, "aaa"}
t:insert{2, "aab"}
t:insert{1, "abc"}
