Add an alias to an index

[Examples](#examples)

## Required arguments

<details open>
<summary><code>alias index</code></summary>

is alias to be added to an index.
</details>

Indexes can have more than one alias, but an alias cannot refer to another
alias.

FT.ALIASADD allows administrators to transparently redirect application queries to alternative indexes.

## Examples

<details open>
<summary><b>Add an alias to an index</b></summary>

Add an alias to an index.

{{< highlight bash >}}
127.0.0.1:6379> FT.ALIASADD alias idx
OK
{{< / highlight >}}

Attempting to add the same alias returns a message that the alias already exists.

{{< highlight bash >}}
127.0.0.1:6379> FT.ALIASADD alias idx
(error) Alias already exists
{{< / highlight >}}
</details>
