# ------
# Basic insert entities:
#     We can insert `The_Lord_of_the_Rings` directly.
#     Here we define a group of data called `Batmans` in form  like `The_Lord_of_the_Rings`.
#     Note that, milvus doesn't support string data, so we comment "title" key-value, and
#     the key of id is required to be `_id`.

# ------
# Basic create index:
#     Now that we have inserted all the films into Milvus, we are going to build index with these data.
#
#     While building index, we have to indicate which `field` to build index for, the `index_type`,
#     `metric_type` and params for the specific index type. In our case, we want to build a `IVF_FLAT`
#     index, so the specific params are "nlist". See pymilvus documentation
#     (https://milvus-io.github.io/milvus-sdk-python/pythondoc/v0.3.0/param.html) for `index_type` we
#     support and the params accordingly.
