| $indexes | array[] | indexes specification. Each specification should be an array in format: optionName => value The main options are: - keys: array, column names with sort order, to be indexed. This option is mandatory. - unique: bool, whether to create unique index. - name: string, the name of the index, if not set it will be generated automatically. - background: bool, whether to bind index in the background. - sparse: bool, whether index should reference only documents with the specified field.
