Enable re-indexation with `indexSwap`

[brunoocasali]

This guide explains how you can reindex the data using the CLI. https://github.com/meilisearch/meilisearch-symfony/wiki/index-data-into-meilisearch#indexing-manually

If you run this operation, you may have downtime since your indexes should be cleaned before doing it.

The idea behind this issue is to apply the indexSwap from the meilisearch-php instance, which it will enable a better usage experience for the users.
