# Field alias
A {doctitle} is a custom name that maps to a specific key within a [dictionary field](https://docs.coveo.com/en/2036/) in your [index](https://docs.coveo.com/en/204/).
You can use field aliases to retrieve multiple dictionary field keys in a single query request.

For example, if you have a `price_list` dictionary field with keys like `regular`, `vip`, and `wholesale`, you can create field aliases such as `regular_price` and `vip_price` to access multiple values simultaneously.

Field aliases require authorization through a [search token](https://docs.coveo.com/en/56/) using the `allowedDictionaryFieldKeys` property, and are only supported in the Search API.
