/**
 *
 * Builds an index from the given options. An index describes an access path to
 * database objects. It is highly recommended to provide a namespace in the options,
 * indexes without a namespace cannot be used to conduct operations (e.g. less than, between, partial, etc).
 *
 * Each model **MUST** have exactly one primary index, i.e. an index without a label. For having multiple
 * access paths, you need to create secondary indexes, which means you need to provide a label. The label
 * **MUST** be unique per model, i.e. each model can have at most one secondary index with a given label.
 *
 * ```ts
 * const primaryIndex = buildIndex({ namespace: 'orders' })
 * const secondaryIndex = buildIndex({ namespace: 'orders', label: 'label1' })
 * ```
 *
 * A converter may also be passed, for values that are not strings or do not default into
 * legal strings for key expressions. For example, time strings are not allowed in key expressions by default,
 * but using `timekey()` as converter will allow you to use time strings as keys.
 *
 * ```ts
 * const primaryIndex = buildIndex({ namespace: 'orders', converter: timekey })
 * ```
